Meet the fascinating tortoise beetle! These tiny creatures might remind you of miniature turtles due to their unique appearance. Found in various parts of the world, they are an interesting species to learn about.
Tortoise beetles are often discovered on plants from the Convolvulaceae family, such as morning glories and bindweeds, as well as the Solanaceae family, which includes potatoes, tomatoes, beans, and peppers. Their presence in home gardens is typically minimal, making their feeding habits primarily cosmetic.
As you delve into the world of tortoise beetles, you’ll uncover intriguing aspects, from their distinctive morphology to their larvae’s behavior. Stay tuned as we explore the little-known features of these charming insects.
Understanding Tortoise Beetles
Tortoise beetles belong to the leaf beetle family, Chrysomelidae, and are classified under the subfamily Cassidinae. Their name is derived from their unique physical appearance that resembles miniature turtles, with a dome-shaped body and a skirt-like edge. They can be quite colorful and are truly fascinating creatures.
When you’re trying to identify a tortoise beetle, pay attention to its size and color. Adult tortoise beetles can vary in adult size, but they’re generally small. Besides, their coloration can change depending on their environment or as a response to disturbances. This color change is due to an optical illusion created by a combination of structural and pigmented coloration.
Here are some key features of tortoise beetles:
- Dome-shaped body
- Skirt-like edge around the body
- Vary in size and color
- Part of the Chrysomelidae family
- Subfamily: Cassidinae
One interesting fact about tortoise beetles is that they primarily feed on plants from the Convolvulaceae (morning glories, bindweeds) and Solanaceae (potatoes, jimsonweed, groundcherries, tomatoes, beans, and peppers) families. So, if you grow these plants, you might encounter these fascinating creatures in your garden!
Keep in mind that tortoise beetles are rarely found in high numbers, and their feeding is mostly cosmetic, which means they don’t pose a significant threat to your plants. Regardless, if you happen to find a tortoise beetle, take a moment to marvel at its unique appearance before you decide what to do with it.
The Life Cycle of a Tortoise Beetle
Tortoise beetles undergo a fascinating life cycle consisting of several stages. They start as eggs and eventually transform into adults. Let’s explore the stages of their life cycle in more detail.
Egg Stage
Tortoise beetles begin their life as eggs, usually laid on the underside of leaves. The female selects a suitable location, ensuring the leaves belong to a host plant to provide food for the larvae once hatched.
Larval Stage
Once the eggs hatch, the larvae emerge. They have a flat, oval-shaped body similar to their adults but with a difference – they carry shed skins and feces on their back. This peculiarity serves as a camouflage, protecting them from predators.
During the larval stage, they feed on the foliage of various plants. Different tortoise beetle species have different preferred host plants. For example, some species feed on anacua in South Texas, while others might prefer sweet potatoes or related plants.
Pupal Stage
After multiple molts, the larvae eventually enter the pupal stage. They will attach themselves to a leaf or bark, form a protective casing, and undergo a metamorphic process. This is when they transform from a larva to an adult tortoise beetle.
Adult Tortoise Beetle
At the end of the pupal stage, adult tortoise beetles emerge, sporting magnificent colors and tiny dome-shaped bodies resembling tiny turtles. They will now search for mates to continue the cycle.
Adult tortoise beetles are also known for their unique feeding habits, as they feed primarily on foliage from the Convolvulaceae and Solanaceae families, including plants such as morning glories, beans, and tomatoes.
In summary, the life cycle of a tortoise beetle progresses from the egg stage, through the larval and pupal stages, and ultimately to adulthood. This fascinating process is just one reason these creatures captivate many nature enthusiasts.
Unique Characteristics of Tortoise Beetles
Tortoise beetles are fascinating insects with several distinctive features. In this section, you’ll learn about their unique characteristics, including their elytra, shield-like appearance, fecal shield, metallic colors, and more.
-
Elytra: The elytra are the hardened front wings that cover the abdomen and provide protection. Tortoise beetles have uniquely shaped elytra, giving them a shield-like appearance.
-
Shield-like appearance: Resembling miniature turtles, tortoise beetles have a dome-shaped body with an expanded outer edge. This shield provides protection from predators and the elements.
-
Fecal shield: A rather unusual defense mechanism, tortoise beetle larvae create a fecal shield from their own waste. This unappetizing shield deters predators from attacking them.
-
Metallic colors: Many tortoise beetle species exhibit metallic colors that can change depending on the angle of light and their mood. Some species can even alter their pigmentation to better blend with their surroundings.
-
Color layers and pigments: The vibrant colors of tortoise beetles come from the layers of pigments beneath their transparent elytra. These pigments help them blend into their environment for protection.
Tortoise beetles display a fascinating ability to roll up their edges when threatened. This behavior, coupled with their unique characteristics, makes them a captivating subject for nature enthusiasts.
Geographical Presence and Habitat
Tortoise beetles are fascinating creatures, and you might be curious about their geographical presence and habitat. These beetles can be found in various regions across the globe, including North America.
In North America, the Eucalyptus Tortoise Beetle is an introduced species from Australia. It made its way to California, and has since spread throughout regions where eucalyptus trees grow, as mentioned in this UC IPM article.
The habitat of tortoise beetles is closely tied to the plants they feed on. They are often found in grasslands, particularly on or near their host plants. Here are some general features of their preferred habitats:
- Found on host plants, such as eucalyptus trees
- Grasslands and open areas with low vegetation
It’s worth noting that the desert tortoise, although not a beetle, shares the habitat with some tortoise beetles and can be found in the deserts of southwestern United States, as described in this USGS article.
In conclusion, tortoise beetles have a diverse geographical distribution and can be found in various habitats, including grasslands and areas where their host plants are abundant.
The Role in the Ecosystem
Tortoise beetles play a significant role in their ecosystem. They are herbivores, feeding mainly on the foliage of plants in the Convolvulaceae and Solanaceae families, such as morning glories, bindweeds, potatoes, and tomatoes 1(https://extension.umaine.edu/home-and-garden-ipm/fact-sheets/common-name-listing/tortoise-beetles/). This feeding behavior helps to control the growth of these plants.
As part of the food chain, tortoise beetles also serve as a food source for various predators. Some natural predators that help control tortoise beetle populations include:
- Parasitic wasps: These insects lay their eggs inside the tortoise beetle larvae, eventually killing them.
- Assassin bugs: These predatory insects attack and consume tortoise beetles.
- Ladybugs: Known as beneficial insects, ladybugs feed on the eggs and young larvae of tortoise beetles.
The presence of these predators in the ecosystem helps maintain a balance and prevent tortoise beetles from causing excessive damage to their host plants. At the same time, the tortoise beetle’s feeding behavior provides a necessary check on the growth of specific plant species.
In conclusion, tortoise beetles are an essential part of the ecosystem due to their plant feeding habits and their role as a food source for various predators. Maintaining a balance of tortoise beetles and their predators is crucial for overall ecosystem health. Keep in mind the importance of preserving the habitats of these fascinating creatures.
Feeding Habits and Diet
Tortoise beetles are fascinating creatures with unique feeding habits. They primarily feed on plants, especially those considered weeds.
For example, they are known to prefer bindweeds, a type of weed. Another favorite food source for these leaf beetles is potato plants, which can become a concern for gardeners.
But don’t worry too much. They also have an appetite for cabbage, corn, and grass. This widespread diet helps control weed populations and occasionally benefits agriculture.
Here’s a comparison table of their feeding preferences:
Food Source | Importance to Tortoise Beetle |
---|---|
Bindweeds | High |
Potatoes | High |
Cabbage | Moderate |
Corn | Moderate |
Grass | Moderate |
As you can see, tortoise beetles have a wide range of feeding preferences, covering many plants in your garden. By understanding their diet and feeding habits, you can better appreciate their fascinating lifestyle and their impact on the ecosystem.
Host Plants and Impact on Agriculture
Tortoise beetles are small insects that can be found in your garden. They can cause damage to a variety of host plants, such as raspberries, strawberries, milkweed, sweet potatoes, morning glories, and other plants in the Convolvulaceae family. Below are some impacts and features of tortoise beetles:
- Their feeding mainly affects the appearance of the plants, as they leave holes in the leaves.
- Infestations can occur when the population of tortoise beetles is high.
As a gardener, you should be aware of the following:
- Tortoise beetles rarely cause severe damage, so control measures are usually not necessary.
- Infestations are more likely to occur in home gardens and less frequently in agricultural settings.
Remember, while tortoise beetles can cause some damage to host plants, their impact is mainly cosmetic. It is essential to keep an eye on your garden and monitor for any signs of infestation. In case you spot these beetles, take the necessary measures to ensure the health of your plants.
Species of Tortoise Beetles
You might encounter various species of tortoise beetles across the globe. However, let’s focus on four well-known species, each exhibiting unique characteristics.
- Charidotella Sexpunctata
- Golden Tortoise Beetle
- Clavate Tortoise Beetle
- Hemisphaerota Cyanea
The Charidotella Sexpunctata, also known as the golden tortoise beetle, dazzles with its metallic appearance. Interestingly, this beetle can change color from gold to a dull reddish-brown and even green, a rare trait in beetles. You’ll typically find this beetle on morning glories and sweet potato plants.
In contrast, the Clavate Tortoise Beetle has a spiked appearance, making it easily distinguishable. This beetle feeds on Solanaceae family plants, such as tomatoes and peppers.
The Hemisphaerota Cyanea species is known as the blue tortoise beetle, owing to its striking blue color. You might encounter this beetle in southern Florida, where it enjoys feeding on the wax myrtle plant.
To better understand the differences between these tortoise beetle species, let’s review the following comparison table:
Species | Appearance | Habitat | Host Plants |
---|---|---|---|
Charidotella Sexpunctata | Metallic Gold | Widespread in North America | Morning glories, sweet potato plants |
Golden Tortoise Beetle | Gold, Reddish-Brown | Eastern US, Canada, Central America | Morning glories, bindweed |
Clavate Tortoise Beetle | Spiked | Eastern US, Canada | Tomatoes, peppers, ground cherries |
Hemisphaerota Cyanea | Blue | Southern Florida | Wax myrtle |
While exploring these tortoise beetles, remember that their appearances and host plants might vary slightly across regions. So, it’s always exciting to discover new species or variations within your area.
Observing and Identifying Tortoise Beetles
Tortoise beetles are small, intriguing insects that look like miniature turtles. To spot them, you should pay close attention to plants in the Convolvulaceae family, such as morning glories and bindweeds, or the Solanaceae family, which includes potatoes, tomatoes, beans, and peppers (source).
When you’re trying to identify these beetles, examine their distinctive features:
- Dome-shaped body resembling a turtle shell
- Transparent and often metallic or iridescent colors
- Legs and head tucked under the body, adding to their tortoise-like appearance
To help with identification, consider visiting bugguide.net, an invaluable online resource for insect enthusiasts. You can search through countless images and find a wealth of information on various species of tortoise beetles.
Now that you know what to look for, take some time to observe and appreciate the fascinating world of tortoise beetles. Remember to approach them gently, as they can be quite delicate. With a bit of patience, you’ll soon learn to recognize these tiny marvels of nature.
Dealing with Tortoise Beetle Infestations
To deal with tortoise beetle infestations, consider using biological control methods. These can be an effective and environmentally friendly option. Introducing natural enemies like damsel bugs, shield bugs, and ladybird beetles can help control tortoise beetle populations. They are known to feed on tortoise beetles, so, having them in your garden can keep infestations in check.
You might also want to try using insecticides when necessary. But beware of the possible harmful effects on beneficial insects and the environment. For example, some insecticides can be toxic to bees. Be sure to choose products specifically designed to target tortoise beetles so as to minimize potential harm. Always follow the manufacturer’s instructions for safe and effective use.
Here’s a quick comparison table of the two main methods mentioned above:
Method | Pros | Cons |
---|---|---|
Biological Control | Eco-friendly, can target specific pests | May take time to establish populations |
Insecticides | Fast-acting, can provide immediate relief | May harm beneficial insects, environment |
Overall, an integrated approach using both biological control and insecticides (when needed) may be the most effective way to deal with tortoise beetle infestations. Make sure to monitor the situation regularly and adjust your strategies accordingly.
Interesting Research and Facts

Letter 1 – Tortoise Beetle Larva on curry in Malaysia: Silana farinosa
Strange Looking Bug Not Identified
February 21, 2010
Hello, I see this bug on the leaves of our curry leaf tree. It doesn’t seem to feed on other tree leaves. Just the curry leaf tree.
mei
Malaysia
Hi mei,
This is the larva of a Leaf Beetle in the family Chrysomelidae, possibly a Tortoise Beetle. Providing the name of the food plant, curry, should make the identification easier. We found a Local Beetles’ Battles page of the Asian Entomology Collection and Studies website, that pictures a Tortoise Beetle, Aspidomorpha deusta, and the quote:
“IN 1994, Universiti Kebangsaan Malaysia entomologist Prof Mohamed S. Mohamedsaid noticed strange white beetles on curry leaf plants. Careful study revealed that the beetles came from a genus restricted to Sri Lanka where it is represented by one species, Silana farinosa, commonly known as the tortoise beetle.
‘The occurrence of Silana farinosa feeding on curry leaves in Malaysia is probably a very recent introduction. It has never been reported before in the country,’ he says.
‘Aspidomorpha deusta’ is a common tortoise beetle east of Java. This foreign species was found on a beach off Kapar, Selangor. —
‘It’s very unlikely that its presence would have gone unnoticed, for the host plant is also an important crop,’ he explains, adding that the leaves of the plant are an essential ingredient in Malaysian cooking, especially curries.
The taxonomist, who works with UKM’s Centre for Insect Systematics, reckons the creatures might have been feeding on dry curry leaves when they were unwittingly packed into someone’s luggage and brought into Malaysia from Sri Lanka.
‘They are real pests as these popular plants are endangered by them,’ he says, adding that the curry leaf plant had never before been attacked by insects as it emits a powerful smell.
More recently, another species of foreign tortoise beetle was found on our shores.
‘In all my years of studying beetles, which included combing the beaches of Malaysia for tortoise beetles, I have never encountered a specimen belonging to the species collected in March last year,’ he says.
According to Prof Mohamed, Aspidomorpha deusta is common from Java eastwards to Papua New Guinea and Australia.”
We then found photos of larval Silana farinosa on the photomalaysia website, and they appear to match your photos.

Dear Ian,
This is a Tortoise Beetle in the tribe Cassidini, and it is similar to this individual on Insetologia. We located an image on FlickR of Cyrtonota cyanea that looks like a very good match to your Tortoise Beetle. We found an image of a mounted specimen on Cassidinae of the World, but dead specimens of Tortoise Beetles often lose their beautiful coloration.
Letter 3 – Antique, Victorian Brooch made with actual Tortoise Beetles
Subject: Scarab Victorian Brooch
Location: Oregon
January 15, 2013 5:09 pm
This brooch had four beetles on it, but one fell off. If you Google, ”green scarab beetle,” lots of pictures of this species come up for sale called, ”antique Victorian brooch.” One website, http://wanderinweeta.blogspot.com/2010/07/ancient-mystery-beetle.html, has the best pictures I have seen where one commenter says it’s not a scarab, but rather, a tortoise beetle (Chrysomelidae). I am interested in your opinion, and whether or not you know if a replacement to fix my brooch is possible.
Signature: Jerry Burke
Hi Jerry,
We agree 100% that these are not Scarab Beetles, but rather, that they are Leaf Beetles in the family Chrysomelidae, possibly Tortoise Beetles in the tribe Cassidini. Here are some examples of North American species from BugGuide. We have never seen this particular species, but we did find other examples online of Victorian jewelry made with these beetles which are incorrectly being called Scarabs, as well as some modern jewelry by Lito Karakostanoglou. We will continue to research this matter.
After finding numerous examples of Victorian Jewelry made with these Leaf Beetles incorrectly identified as being Scarab Beetles, we finally found the Mid-19th Century Jewelry website with this image correctly identified as being earings made of Tortoise Beetles. The Evolution website has a pair of earrings with the species identified as Desmonota variolosa with this information: “Tortoise Beetle Earrings – Desmonota variolosa The tortoise beetle is a member of the leaf beetle subfamily. These tortoise beetles have been mounted on a pair of sterling silver earrings. Their beautiful green sheen is sure to attract attention and open the wearer up to a host of compliments.” You might want to consider ordering a pair of earrings from Evolution and having a jeweler replace the missing Tortoise Beetle in your brooch. According to Encyclopedia Britannica: “The pits and grooves covering the South American leaf beetle Desmonota variolosa give it an iridescent green colour with depth resembling that of an emerald.” There is a nice image of these beetles in the Hunterian Museum & Art Gallery Collections website. We have given up hunting for a photo online of a living Desmonota variolosa, but we just thought of a new search idea.
We did find a similar looking red Tortoise Beetle from Costa Rica on the Nature Closeups website that is identified as being in the genus Spaethiella. We also found a gorgeous blue and red Tortoise Beetle from the Amazon on Green Tracks News identified as being in the genus Eugenysa. Alas, we could not find any images of living Desmonota variolosa. If any of our readers get lucky enough to find a photo of a living specimen of Desmonota variolosa, please comment on this posting.

Hi Tom,
This beautiful insect that looks like a drop of gold paint is a Golden Tortoise Beetle, Charidotella sexpunctata, and it feeds on the leaves of morning glories and other plants in the family Convolvulaceae. Golden Tortoise Beetles are capable of changing colors, and much to the dismay of insect collectors, they lose their lovely golden color after death. See Bugguide for additional information on the Golden Tortoise Beetle.

Dear HEIDEN999,
These are Tortoise Beetle Larvae in the tribe Cassidini. Knowing the plant they were feeding upon might help to more easily identify the species. We have not had any luck finding an exact match to your species, but there are many similar looking examples in our archives and on the web.
hi daniel, thanks for the fast ID on my weird larvae. so they are tortoise beetles hey ..well these beautiful tortoise beetles happen to be close by perhaps this is an adult??? I have sent an attached image. it looks like they are feeding on the same type leaf. could this be a match??? thanks, gary heiden
Hi Gary,
Based on the information you have provided, we believe it is an excellent possibility that the adult Tortoise Beetle feeding on the same plant is the same species as the larvae. We could not locate a match on the World’s Best Photos of Cassidinae Flickr Hive Mind website.

This Leaf Beetle, Desmonota variolosa, is native to Brazil, not England. We first encountered this Leaf Beetle when we tried to identify the insects used in the making of an antique brooch, a common practice in Victorian times. New jewelry is also available using these real beetles. There are plenty of links on that posting to follow our original research. You can also find a mounted specimen pictured on the Hunterian Museum & Art Gallery Collections site.
Thank you so much, the girls will be so happy to finally know what it is and that it’s used in jewellery!

Letter 10 – Geiger Tortoise Beetle from Grand Cayman
Gold/green transparant beetle
Tue, Feb 3, 2009 at 9:46 AM
Hi Bugman,
I live in on Grand Cayman. Whilst volunteering for the Blue Iguanas at the Botanical Park last week, this beetle came out of the bucket of leaves we had collected. I can’t seem to find it on any websites so I need your help!! I have attached some photographs which should help with the ID. The transparent shell was over the wings (but split like a ladybird) and the inner half of this was coloured gold and green and speckled with blue. It had a 3rd part to the transparent shell which went over it’s head like a shield bug. The underside of it’s abdomen was also shiny. Total length maybe about 1 centimetre. It was quite happy walking around (trying to navigate my hairy arms!) but when my frined picked it up so we could get a photo of its underside it ‘crouched’ so it was very difficult to pick up.
I’ve attached some photos for you but have lots more (including one of it about to take off!) let me know if you would like to see some more.
Thanks! Emily
East End, Grand Cayman
Hi Emily,
This is some species of Tortoise Beetle. Tortoise Beetles are Leaf Beetles in the tribe Cassidini. The gorgeous metallic coloration vanishes after the insect dies, so mounted Tortoise Beetles in collections are not as beautiful as they are alive. Some Tortoise Beetles are called Gold Bugs.
Update: Monday, February 6, 2009
Daniel:
This looks like a tortoise beetle in the genus Eurypepla ( Chrysomelidae : Hispinae : Ischyrosonychini [=Physonotini]). It looks very much like E. calochroma, the Geiger Tortoise Beetle, varieties of which are found in south Florida and the Bahamas. Closely related species occur in Cuba (E. vitrea) and Jamaica (E. jamaicensis). Distribution information is very hard to find and it could be any of the above. Bugguide has some excellent images of the Geiger Tortoise Beetle, under the name Physonota calochroma. Apparently the generic placement of this species has been debated for a long time, but the current trend appears to lean toward Eurypepla. The Geiger Tortoise beetle is considered a mild pest in Florida where its preferred host is the Geiger Tree (Cordia sebestena). Regards.

Eggplant tortoise beetles?!
January 25, 2010
Hi,
Last summer I started finding these tortoise beetles in central Oklahoma. They are translucent green, about the size of a pea, and have a smooth “shell”. I think that they might be eggplant tortoise beetles, but I’m not sure. Thanks for the help.
Josh Kouri
Hi Josh,
We believe you have correctly identified the Eggplant Tortoise Beetle, Gratiana pallidula, though your letter did not indicate the plant that the specimens were feeding upon. Often a food plant is a critical factor in the correct identification of an insect. According to BugGuide, the Eggplant Tortoise Beetle feeds upon “several species of Solanum (tomato family: Solanaceae).“
Sorry, I wasn’t sure what species of plant they were found on. I did some research on the Solanum family and was able to identify the plant the beetles were feeding on as /Solanum elaeagnifolium, /the Silverleaf Nightshade. Hope that helps,
Josh
Thanks Josh,
That is consistent with the preferred host plants for the Eggplant Tortoise Beetle and tends to confirm the identification.

Hi Bugman!
We live in Tucson and have had a lot of rain this year. We took the kids to the waterfalls at Tanque Verde and found a few of these odd bugs. They look like a cross between some kind of caterpillar and a scorpion (at least how the tail curls up?)
They were right near the shrubs by the water and some just on the rocks. I have been here 11 years and never come across these before- I am thinking its a larvae for something? Any ideas?
Signature: Lara
Dear Lara,
Five years ago, we had some difficulty trying to identify the Arizona Tortoise Beetle Larva, Physonota arizonae, but now there are more images available online. The shrub upon which you found them is most likely the Canyon Ragweed. It is interesting that the images you provided show two projections at the tip of the abdomen, while our previously posted images show fecal droppings carried at the tip of the abdomen, so we presume the projections have adapted for that purpose, perhaps as camouflage or to make the larva less appetizing. Many species of Tortoise Beetles have larvae that behave similarly.

Hi Robert,
According to BugGuide, the Australian Tortoise Beetle or Eucalyptus Tortoise Beetle, Trachymela sloanei, was: “Introduced from Australia. First recorded in 1998 in California.” BugGuide also indicates that it feeds on Eucalyptus, and there is no indication it feeds on citrus. The County of Los Angeles Agricultural Commissioner has an excellent pdf on this “new agricultural pest for Southern California.
Thank you so much for the ID on this beetle. It just so happens that we have two huge Eucalyptus trees in our yard. Somehow he found his way to the citrus.
Thanks again.

My kids and I have had trouble id’ing the following insect that we found on my wife’s van last night. It looks like–and is exactly the same size as–a typical ladybug. We live in southern California.
Many thanks,
Russ
Hi Russ,
We didn’t recognize your Tortoise Beetle species, so we did some web searching. We located this site through the County of Los Angeles Agricultural Commissioner that states: “New Agricultural Pest for Southern California Australian Tortoise Beetle, Trachymela sloanei Introduction: In early February, 1998, Australian Tortoise Beetle (ATB), Trachymela sloanei , was detected for the first time in western Riverside County at a private residence containing acreage of Red gum eucalyptus (Eucalyptus camaldulensis ). A specimen of the new beetle was noticed by the owner and taken to the Department of Entomology, University of California, Riverside, for identification. The find represents a new record not only for California but also for the New World. ” As the insect feeds on the leaves from a plant native to its own country and not southern California, it was inevitable that it would one day enter our closely guarded borders, following the Eucalyptus Tree Borer and other Australian insects that like the California climate where their host plants thrive without natural pests. It is said that eucalyptus trees are the commonest trees in southern California, but their numbers are dwindling due to the introduction of insect pests. Thank you for contributing this new species to our archive.

Dear Frank,
We are in awe of the bold, complimentary colors of this stunning Tortoise Beetle in the subfamily Cassidinae and tribe Cassidini. This Peruvian Amazon relative pictured on FlickR bears a resemblance and we would would not doubt they might both be in the genus Eugenysa, or this individual also on FlickR and also from Peru and also tentatively in the genus Eugenysa.

Hi!
I was wondering if you could help identify this beetle I found this month while trekking about in Guanacaste, Costa Rica. I’ve looked through your index of beetles and checked the bug guide and haven’t found a match. It kinda looks some sort of tortoise shell beetle. In the past your site has been a wonderful source for my insect hobbies. Thanks for your hard work. 🙂

Hi Sarah,
You are correct that this is a Tortoise Beetle in the tribe Cassidini, but we do not know the species. It sure is a pretty beetle.

I found this bug on our property in town but in an area that just grows what ever but it is mowed.
it was found on the plant in pictures, in Clayton, New Mexico, USA I was just curious what it is as I have never seen one like it.
Signature: Ayla S.
Dear Ayla,
This appears to be a Tortoise Beetle Larva in the tribe Cassidini, similar to this Thistle Tortoise Beetle larva pictured on BugGuide, however we are not convinced that is your species because BugGuide data does not include any New Mexico sightings, though there are Colorado sightings. The description of where they were found is consistent with the BugGuide habitat: “weedy fields and waste places where food plants grow.” BugGuide lists the food as “various Asteraceae, incl. thistle (Carduus, Cirsium, Onopordum) and knapweed (Centaurea) spp.” and the leaves pictured in your image look to us like they belong to the aster family. There are other members of the genus and we suspect their larvae look similar, but the most specific we are comfortable responding is that this is a Tortoise Beetle larva from the tribe Cassidini.

Letter 23 – Green Stink Bug Nymphs, Mottled Tortoise Beetle and Marbled Orbweaver from Canada
Subject: These bugs are everywhere!
Location: Vaudreuil-Soulanges, Quebec
August 9, 2012 8:59 pm
Hi there,
I’m a bug friendly person(no bug squishing in this house!)and always take the time to really check out and appreciate any bugs I have come across. Now that I have kids, they are really getting into bugs as well.
I’ve been out in the country for 13 years now and have never come across the bug in picture #1, however, this year they are literally everywhere… On the back deck, on the house, in the house, on shrubs, on the cars and garbage cans, etc…The other day my 8 year old son collected over 20 in under 10 minutes just in a small area around our back door. I went to check on my garden the other day and found a bunch on one of my corn stalks. I thought it might be some kind of stink bug because of the shape, but haven’t found a pic of one that matches. Also of all the ones we have collected and shoo-ed out of the house, none of them stank at all. What are they?
While I’m at it, I’ve attached 2 more bug pics that I would like ID’d. I found bug #2 crawling on a rock and was taken by it’s shiny gold green shell/markings.
Bug #3 is not a bug, but a spider. This fat guy has been living above my backdoor and seems to become active only at night. I thought it was some kind of orb weaver, but couldn’t find a match.
Thanks for any help!

Hi Cindy,
Normally we do not like to include “bugs” from different categories in the same posting unless they have a distinctive relationship to one another, like predator and prey, however, all of your inquiries are either interesting, timely or unusual, so we are making an exception. Additionally, all of your photos are quite nice. The numerous insects are Stink Bug nymphs, and we have been receiving many identification requests for them in the past week. Despite their black coloration, these are Green Stink Bug nymphs, Chinavia hilaris, and you can compare your image to this photo from BugGuide. Another common name for this species is Green Soldier Bug according to BugGuide which states they are: “extremely polyphagous: recorded from 20 plant families(5); adults and older nymphs prefer developing seeds and fruit. May be a pest on soybean, cotton, fruit trees (esp. peach), and many vegetables.”
The green beetle is a Mottled Tortoise Beetle, Deloyala guttata, and according to BugGuide: “larvae and adults feed on leaves of Convolvulaceae (morning glory family).”
The spider is an Orbweaver, and we believe we have correctly identified it as a Marbled Orbweaver, Araneus marmoreus. This is a highly variable species, but we located a matching photo of a white individual on BugGuide. It was also found in Canada.
Thank you for the quick reply! The kids and I have enjoyed reading up on our new buggy friends. I’ll definitely be sending in a few more bug pics that I haven’t been able to ID, sometimes typing a general description into Google gets me hundreds of pages to go through, being stuck on dial-up certainly doesn’t help! Liked you guys on Facebook as well 🙂

Hi, Bugman! I was searching something I could send, it seems to me that you only have a single request of a Coraliomela leaf beetle. We call it “(falsa) barata-do-coqueiro (false) coconut-tree cockroach. It seems that the common name cockroach is because of the larval stage appearance.

Hi Cesar,
Thanks for sending us images of this unusual Leaf Beetle. The images with your hands as scale are fascinating because we do not have North American Leaf Beetles that attain that size. According to the Integrated Taxonomic Information System (ITIS) page, it is classified as a Tortoise Beetle in the subfamily Cassidinae.

I found this very pretty looking beetle on a tree after a hike, my initial thinking is that it may be a form of ladybird or leaf beetle due to it’s shape, but I can’t seem to locate it or anything really close to it.
It has an almost pearl like sheen to it and the outer wing shells are clear at the bottom near its feet.
Anything you could do to help would be greatly appreciated.

Dear Ian,
This is most definitely not a Lady Beetle, but we agree that it is a Leaf Beetle in the family Chrysomelidae. Though we could not find a match on the Brisbane Insect Website, it looks like it might be in the genus Chrysophtharta, so it would be classified as a Tortoise Beetle in the subfamily Chrysomelinae.

I found this little creature 2 days ago, sitting quietly on a leaf in a park just outside of Taipei, Taiwan. It’s about one centimeter long, and it wasn’t moving; just sitting there minding its own business. A quick image search shows “slug moth” as a possible candidate, but I couldn’t find anything quite like it. Any ideas? Many thanks! 🙂
Signature: Robert
Dear Robert,
In our opinion, this is most likely a Leaf Beetle Larva, probably a Tortoise Beetle Larva in the subfamily Cassidinae and not a Slug Moth Caterpillar. It looks similar to this individual from Belize from FlickR as well as this individual from our archives.
Dear Daniel,
Thank you so much for identifying my photo as belonging to a Tortoise Beetle larva! I think you were spot on, as I took the photo only 2 minutes after I photographed a Mottled Tortoise Beetle only a meter away. The larva is so eye-catching that I didn’t make the connection, but now I can clearly see that the black markings on the adult beetle wings mirror the black markings on the larva. I’ve attached photos that I took of each.
Kind regards,
Robert
Dear Robert,
Thanks so much for the update. We cannot say for certain that the Tortoise Beetle and the larva are the same species, but their proximity to one another is a stronger indication than the similarity in the markings as adults often differ drastically in appearance from the larvae.

I am from the Philippines and I love insect photography. These last couple of weeks, I have been taking photos of golden tortoise beetles. Some are here: in this set. I don’t know the exact name of this kind of tortoise beetle. Those spots on the edge of their shell make them different from these beetles: http://bugguide.net/node/view/8826 Could you help me find out the exact species name? Thanks in advance.

Hi Maria,
Your Tortoise Beetles are beautiful. There are certain species in the U.S. that are metallic in coloration and they are sometimes called Goldbugs. Tortoise Beetles belong to the tribe Cassidini. We located another image of your species on Flicker, but without a scientific name. One click away we identified Aspidomorpha miliaris on a Tortoise Beetle page. It is also called the Spotted Tortoise Beetle and the Fool’s Gold Beetle. It is great that you have also included an image of the spiny larvae of the Spotted Tortoise Beetle

How ironic. I got a couple images of one of these myself the other day, in Pima Canyon, in the same mountain range. You can thank Margarethe Brummermann for telling me what it was. Here’s a link with images of more larvae and adults:

Pretty cool, eh? They are quite large by tortoise beetle standards….
Eric
Hey
I looked on your website and there was a leaf larva from Thailand? that looked
similar which was a tortoise beetle. I did some googling and think I found it.
It’s the larva for the Arizona Tortoise Beetle (Physonota arizonae). I remember
seeing these beetles in Sabino Canyon, very pretty! Thanks for your help.
Chris
Hi Daniel and Sonoran Inquiry:
It does look like a Leaf Beetle larva and I think it is probably a Tortoise Beetle (Chrysomelidae: Cassidinae). I think it might be an Arizona Tortoise Beetle (Physonota arizonae), also known as the Arizona Gold beetle. The Bugguide has a fairly good match, and the site ‘Arizona: Beetles Bugs Birds and more’ has a picture of larvae that look even closer (scroll down a little). The host plant is given as various Asteraceae, but particularly Canyon Ragweed (Ambrosia ambrosioides). If that looks like the right plant (it looks similar from what I can tell) then perhaps this is an Arizona Tortoise Beetle. In any case, I think it something very close to that. Regards. K

Dear Gawie,
We believe this resembles the larva of a Tortoise Beetle in the tribe Cassidini, but we have never seen this exact species. We are more familiar with specimens found in North America. BugGuide has a photo of the larva of Cassida rubiginosa, which is typical of the larvae of other Tortoise Beetles. They are often spiny and carry about their shed exoskeletons much like the individual in your photo.

Dear Di,
These are NOT Caterpillars, the larvae of butterflies or moths. Rather, they are beetle larvae.

Perhaps one of our readers will be able to provide some more specific information.
Letter 35 – Spiny Mystery Thing is Tortoise Beetle Pupa
Unidentified armored insect.
Hello,
I just spent half an hour or so looking over your site. It is really a great resouce. Most of the time I put the univerity level entomology courses to work and identifiy my own finds, but since my primary goal is to get a good photo rather than collect, kill and key out these days I was unable to (excuse the expression) pin this one down. This well armored and prickley insect was found in the folds of a Canada Thistle. Just as a guess I would guess some sort of hemipteran – but I defer to your expertise on this one. The location is Grand Island, New York – an island in the middle of the Niagara River. If interested, other fauna and flora photos from the island may be viewed at: http://www.isledegrande.com/naturepage04-v2.htm
Your time in looking at this one and replying is most appreciated. If you can use the image on your site, please feel free to.

OK, so I know there are more types insects than any all the other types of creatures put together, and asking you about an insect from ASIA is asking a lot, but I went on a trip through Vietnam and found this little guy on a sign near a beach close to Danang and it’s so weird! I can’t find anything like it. I live in China and see weird bugs all the time, but can usually put them in some sort of category of the bugs I know back home in the states. (okay, so I live in an urban jungle of 20 million people, but I still see crazy insects)
This thing had some sort of CLEAR shell over a more normal looking shell. It was probably 3/4 of an inch long and didn’t budge. I now wished I would have poked it a bit to see how it moved, but I wanted to leave it alone. Probably the nice choice. It looks like a beetle, but I thought it might even be some sort of true bug in a stage of metamorphoses? Heck, I dunno. But I’ve googled all sorts of combinations of transparent, clear, and beetle, and can’t find much more than tricked out Volkswagons.
Help me, Whatsthatbug! You’re my only hope!

This was found friday aug. 22nd, in a meadow on a grass. It did not seem to be feeding on the plant. We found it during our search for monarch caterpillars.

Dear Jillian,
We knew immediately that this creature is a Tortoise Beetle Larva, and that thing on the end of its tail is excrement. We felt it could not be an Arizona Tortoise Beetle, Physonota arizonae, but we also believed it was closely related. We believe it is the Sunflower Tortoise Beetle Larva, Physonota helianthi, which we identified on BugGuide and that belongs in the same genus. According to BugGuide: “Food: hosts on members of the aster family, Asteraceae.”
Thank You so graciously from our staff, to yours!
We have been identifying a lot of species, and that one gave us a hard time. It was a larva stage, I suppose that’s why. We were able to find and identify a cicada wasp, that was interesting study also.
I wont take up more of your time than necessary, I know it’s precious.
Thank You so kindly,

Hi Jeannie,
Your pretty green beetle is a Thistle Tortoise Beetle, Cassida rubiginosa. According to BugGuide it is also called a Bloody Nosed Beetle which “supposedly refers to the beetle’s ability to secrete a reddish liquid from its head, giving rise to its other common name.” BugGuide also indicates the Thistle Tortoise Beetle was accidentally introduced to Canada in the early twentieth century from Eurasia and it has since spread south to the eastern U.S. Because it feeds upon some introduced thistles and other nonnative weeds, the Thistle Tortoise Beetle was intentionally introduced to Virginia where, according to Bugguide, it “has been used in biological control of thistles. It can reduce thistle vigor and survival, particularly in vigorous grass, but its impact is usually restricted by parasitoids.”

I cannot tell you an exact species name since I don’t have a guide to Chineese Beetles, but it is a Tortoise Beetle, Family Cassidinae. They get their name from their form.

Interestingly, while researching this on BugGuide, we found your photo and the current opinion there, as posted by Ron M is: “Although the golden shine… …doesn’t match any examples currently in the guide, I think it will be Clavate Tortoise Beetle (Plagiometriona clavata) but please wait for other opinions.”

Dear Siggy,
You have two distinct insect orders represented in your request, and at least two, and possibly three different species. The “metallic green bug” is actually a Tortoise Beetle, and we believe it is in the genus Omocerus based on an image we located on The Befuddled Loris (scroll down) and verified on the Coleoptera of Costa Rica where it is identified as Omocerus casta. This same beetle can also be found on the Smithsonian Tropical Research Institute and Discover Life.
The other two creatures are Hemipteran nymphs and we believe they are different species. They are most likely Stink Bugs in the family Pentatomidae.
Daniel,
Well that clarifies things a bit. I found several of each kind of the insects I sent images of in the same small area, so I thought they must be of the same species. Thanks for taking the time to respond.

Hi Miles,
We are at the end of your identification requests, and we decided to split up your beetle requests to better align with are archives. These two beetles are both Leaf Beetles in the family Chrysomelidae, and the black specimen with the orange spots is, we believe, a Tortoise Beetle in the tribe Cassidini. In our attempts to identify it, we stumbled upon a Tropical Diversity in the Amazon blog with a similarly marked, though obviously different species of Tortoise Beetle, and it was just posted yesterday. We then found a Discover Life website with numerous links, and our first click fortuitously led us to an image of your Tortoise Beetle which was identified as Stolas cuculata. We verified the identification on the Biol.uni website. In our attempt to answer your question, we did find a photo on Flickr that appears to be the same species as your Leaf Beetle, but alas, it has not been identified. We are trying to click through all the links on the Discover Life Website in the hopes to properly identify your Leaf Beetle, but we need to attend to other things at the moment.
Hi Daniel,
that’s brilliant, thanks for al of your help with identification. Great idea for a website and I am shocked that you replied so quickly. I might have one or two more….

Identification thanks to Karl
Hi Daniel and Miles:
The leaf beetle in the lower photo is probably Zygogramma violaceomaculata (Chrysomelidae). Zygogramma appears to be a recent re-classification; older references designate it as Calligrapha violaceomaculata. The Electronic Biologia Centrali-Americana also provides an illustration under the older name that looks pretty much identical. Regards.

How you want your letter signed: LG
Dear LG,
We quickly found your Tortoise Beetle, Chelymorpha cribraria, on Featured Creatures where it states: “The genus Chelymorpha Boheman contains more than 100 species, which are mostly Neotropical in distribution. Two species have been recorded (Blatchley 1924) previously from Florida: Chelymorpha cassidea (Fabricius) and Chelymorpha geniculata Boheman. The endemic Florida Chelymorpha geniculata has had a checkered taxonomic history. It is often considered either a synonym or subspecies of Chelymorpha cassidea (Balbaugh and Hays 1972). Both are uniformly tan to red-brown in color with 12 to 14 black spots on the elytra and four to six on the pronotum. Chelymorpha cribraria is extremely polymorphic in color (Vasconcellos-Neto 1988), and most of the color forms have been described as separate species. Only two color forms have been found in Florida so far. The most common color form in Florida is bicolored, with pronotum black and elytra brick-red or tan. Much less common is the color form having a tan ground color with metallic reflections, numerous black speckles, and longitudinal red stripes on the elytra.” According to BugGuide: “adventive in FL (established), native to S. America & West Indies” and “showed up in so. FL following hurricane Andrew (Sep. 1993). ” The species has no common name.

Dear Don,
There has long been a tendency for humans to anthropomorphize rocks, clouds, and even darkened spots on tortillas, and this tendency is probably what lead primitive humans to begin making primitive art. We are thoroughly amused by your perception of the countenance of Darth Vader on the elytra of this Tortoise Beetle. Thanks for sharing your observation.

Location: Cuyabeno National Park, Sucumbios, Ecuador
September 5, 2015 4:15 pm
Greetings bug-men and -women!
My name is Josh and my home is San Diego, California. Working in a pharmaceutical lab during the week, I always enjoyed indulging in the inkling in the state parks around where I live to get out and see the flora and fauna. Although I haven’t traveled much most of my life, this summer my friends were able to persuade me to go with them to Ecuador in order to tour its Amazonian and Andean reaches! Although the diversity was expected, nevertheless I was stunned by the simply unhinged assortment of birds, monkeys, and especially insects. Harboring only a very amateur level of knowledge of some scientific classifications, I was able to do research and figure out each of the insects seen on the voyage, except for one!!! The insect (or possibly even a mollusk?) I would like to present really threw me for a loop. My tour group was on its way on foot to a Siona community about longitudinally midway in the Cuyabeno National Park in Ecuador. I was falling behind the tour, so I was onl y able to snap 1 quick photo of the little guy. Anyhow after some exhaustive searches upon my return home my findings were inconclusive. If you ever find the time to take a look at it, I’d love to know what this peculiar guy was. Then I’ll be able to revise my current slang name for it, the 1934 Tatra 77, of which it bears remarkable resemblance. 😉
Signature: Sincerely, Josh
Dear Josh,
This is most definitely a Tortoise Beetle in the Leaf Beetle tribe Cassidini. We found a matching image on Getty Images, but it is not identified to the species level. Similar looking images on FlickR and again on FlickR are not identified more specifically. At this time, the best we can do is the general identification.

Wildboy
New Territories, Hong Kong
Hi there Wildboy,
This is a Tortoise Beetle in the tribe Cassidini, but beyond that, we cannot tell you much of the exact species. The jelly like cushion is actually part of the elytra or hardened wings of the beetle that cover and protect the membranous flying wings. Many beetles that have this type of metallic coloration quickly fade when they die.

We have noticed that you have sent a few emails over the past week and we have been very bad about posting any of your submissions. This is not a Ladybug, and for the record, Ladybugs are more correctly called Lady Beetles. This is a Tortoise Beetle and they are known for their iridescent colors, however, once the Tortoise Beetle dies, the colors fade.

Dear Zebith,
Thanks for working with us to create this posting. We hope you understand why we cannot post images downloaded from the internet when there is no permission from the photographer. This Dobsonfly posting addresses the complicated issues of Copyright Infringement and also illustrates the problems we encounter when there is no permission to use images. This Eucharitid Wasp image is another example of plagiarism we have encountered on our site.
We began our search using the common name Tortoise Beetle coupled with first Guyana, and then neighboring countries like Suriname, Brazil and Venezuela, but all produced no matching images. We then turned to the scientific name for the Subfamily Cassidinae that includes Tortoise Beetles, and we struck gold with this pdf on BioLib entitled Tortoise beetles of the French Guyana – a faunistic review (Coleoptera: Chrysomelidae: Cassidinae) by LECH BOROWIEC1 and GÉRARD MORAGUES, but alas, there are no illustrations, though there are numerous scientific names of the species found in French Guyana. Searching for images for each of those names might take weeks, and though we do not have the time, you may. We then tried to search the subfamily name coupled with other nearby countries, and when we found this unidentified Tortoise Beetle from Peru in our own archives that we suspect might be in the genus Eugenysa, we decided to search that name as well, but again to no avail. Though we drew a big blank, we are going to put out a request to our readership, including Cesar Crash of Insetologia from Brazil and to Karl who loves a challenge, to assist us in this ID. You might also try to contact LECH BOROWIEC1 and GÉRARD MORAGUES to see if they can assist you. If you do eventually score a species, or at least a genus ID, please let us know.
Thank you so much for all of your work! I will continue the search and hope that the tendrils that we both are putting out there will bring back an answer. Fingers crossed!
As far as the copyright, I appreciate your policy. As an artist, I deeply appreciate when people make sure others only post images that they have direct permission to use. Thank you for upholding these respectful (and legal) standards!

At first we thought this was a Slug Caterpillar, but the curious thing about your image is the debris on the back. We enlisted Eric Eaton’s assistance to identify a Tortoise Beetle Pupa, and then Nathan wrote back correcting this misidentification.
Update (04/17/2006)
I believe, now that you were able to identify the tortoise beetle larvae photo I sent you can also put the following entry to rest as well. I found it under the first Caterpillar listing. It looks very similar to an already identified toroise beetle larvae photo found on one of your beetle pages – it too was green like this one. Again, great site!

Something like a Crowned Slug Caterpillar?
Location: Rolla, MO
April 29, 2012 11:49 pm
There were several of these on the Chinese lantern plant I purchased last year. I thought I’d removed them all, only to find they had multiplied and prospered at the expense of my plant while I was on vacation last year. The neat thing about them is that they carry some sort of baggage! They usually have it settled across their back, but sometimes carry it up high in the air. Perhaps they’re trying to camouflage to look like some sort of excrement?
Signature: Michelle Nash, Rolla, MO
Dear Michelle,
You are being troubled by the larvae of a Tortoise Beetle, most likely a Clavate Tortoise Beetle. These beetles feed on plants in the tomato family including Chinese Lantern. You may also compare your photo to this image posted to BugGuide. Your observation about the baggage is correct. According to the Featured Creatures website: “The larva is a typical tortoise beetle type, but very unlike most other beetle larvae. The last abdominal segment has a special “fecal fork” which permits the attachment of dried fecal matter. This fecal mass is carried over the dorsum in the same form as “trash bugs” (Neuroptera), and presumably offers a degree of protection through camouflage. The body is green, flattened, and almost entirely fringed with whitish multispiculate projections.”

Signature: Howard
Dear Howard,
This is a Tortoise Beetle Larva, and we think chances are very good that it is a Golden Tortoise Beetle larva, Charidotella sexpunctata, based on this BugGuide image. According to BugGuide, they feed on “leaves of various Convolvulaceae” the family that includes morning glories, and many species have heart shaped leaves. The spiny larva of many Tortoise Beetles produce a fecal shell of droppings that acts as camouflage or protection.
Daniel,
I appreciate the response. I’m 47 and have read many sci fi books. I didn’t know if this was a bug I didn’t recognize or if I needed to contact the CDC.

Dear Christina,
This is the larva of a Tortoise Beetle and it is carrying its own feces which it uses as camouflage. We believe it might be a Clavate Tortoise Beetle larva, which is pictured on BugGuide.

Letter 64 – Tortoise Beetle Larva: A correction
Correction on Crowned Slug Caterpillar ID
Dear Bugman,
In regards to " Crowned Slug Caterpillar (07/14/2005) Strange bug", I do believe the key word in the sender’s question is "vine" as this is not a caterpillar, but the very minute larva of the Golden Tortoise Beetle, Metriona bicolor. I’ve had oodles of them myself on my decorative sweet potato vines and they will "shotgun" pattern the leaves to the point of decimating the plant (one characteristic hole is partially visible to the left of the larva). They use their fecal pellets as a dorsal shield which they elevate when alarmed, hence the "dark thing" falling off (probably physically knocked off when poked.) I’ve been keeping a culture of them for a couple years now and hope to be publishing some research on them in the not-too-distant future. I haven’t taken any macro shots of the larvae myself, but check out the link below and I think you’ll see that the clarity/quality of the photo on your site makes it appear to be much larger than it is in reality. [see this site]
The adults are fascinating in that they can change color, from a dun/CLEAR tannish color when disturbed (below) to a shining gold when feeding and at rest. Truly gorgeous; like drops of molten gold! Keep up the good work,

Greetings Bugman,
Can you help me with the identification of this bug please. Found it on a leaf on the Island of Ilha Grande, south west of Rio de Janeiro in Brazil. The picture was taken at the end of August 2007.
Thanks, Steve
Ilha Grande, Brazil
Hi Steve,
This beauty is a Tortoise Beetle in the tribe Cassidini. We spent the day getting knee surgery and this is our first posting today. We don’t want to take the time right now for a species identification before trying to post a few additional letters. Perhaps our invaluable contributor Karl will be able to take a stab at this one. We just realized that it is the first of the month, and we have problems with new images posting live at the beginning of each month.
Update from Karl
Hi Daniel:
I believe this Tortoise Beetle is in the genus Stolas (Chrysomelidae: Cassidinae). The tribe is Stolaini, although in some references the tribe is given as Cassidini. Stolas is a rather large genus (170+ species) with considerable variety in size, shape and color, and a half a dozen or so species look similar to the one in Steve’s photo. The closest I could find was S. stevensi (how is that for coincidence?!). It’s not a perfect match but it is the only one I could find that has the yellow/gold markings on the pronotum. There is probably some variability within the species and that may account for the small differences; or it could be a case of sexual dimorphism. I could find little information about the species, but the southeast coast of Brazil is within its range. Regards.
Karl
Update: June 28, 2014
Thanks to a comment from a Park Ranger in Ilha Grande, we now know that this is Stolas stevensi or a closely related species in the same genus. The Cassidinae of the World website has corroborating images.
Update: Comment December 18, 2014
In the meanwhile I am pretty sure (as sure as one can be ;-)…!) that this one is Mesomphalia turrita.

Dear Ariel,
Thanks for presenting us with this challenging identification. Our initial search did not provide us with any conclusive identification, but we strongly suspect this is a larval form and that it will mature into some species of Beetle. Many Leaf Beetles in the family Chrysomelidae construct structures made of fecal matter to camouflage them while they are feeding. Perhaps one of our readers will be able to provide an identification.
Thank you for your help Daniel! I look forward to more info from your readers.

Hi Daniel:
I am fairly certain that Dean’s tortoise beetles belong in the genus Physonota. Of the several species occurring in Nicaragua, Physonota attenuate appears to be the closest match. Unfortunately, all of the reference photos I could find of this species are of preserved museum specimens, and tortoise beetles don’t preserve their color or clarity when they are dried. A live specimen would look much like the related North American species, P. helianthi, which can be viewed at the Bugguide site. Regards.

(Plus, it’s a really cool photo and I wanted to share it.)
How you want your letter signed: drsunsets
Dear dr sunsets,
This is a Leaf Beetle in the family Chrysomelidae, and we believe it is a Tortoise Beetle in the tribe Cassidini, but we didn’t read your submission that carefully, and we thought you took this image in The Netherlands, so we did not find any matching images. We will attempt a new search of Caribbean species. A quick search turned up no matches. Perhaps one of our readers will have better luck.
Wow, thanks so much for your quick reply!
Letter 77 – Unknown Tortoise Beetle Larva on Iris Leaf
Yellow and Black Bug
Hi. I’ve loved taking pictures of strange insects, etc. and I came across this bug (and several others in clusters) in my Iris flower bed a few weeks ago. Could you please identify it for me? I’d greatly appreciate it.
Dawn from OK
Talala, OK US
Hi Dawn,
This is a Leaf Beetle Larva in the family Chrysomelidae. We are nearly certain it is one of the Tortoise Beetles in the subfamily Cassidinae. We found a photo on BugGuide that is a very close match. Sadly, we haven’t the time to research the exact species that feeds on iris at the moment, but perhaps one of our readers will submit a comment.
Letter 78 – Wild Olive Tortoise Beetle Pupa from Costa Rica
Subject: Indentify bug
Location: Cartago, Costa Rica
July 17, 2015 9:59 am
Hi Mr. Bugman, I found a weird bug, but nobody can tell me what kind of bug is, maybe you can help me to to identify it. Thank you so much
Signature: Jc Nuñez
Dear Jc Nuñez,
Wow, you nearly had us stumped. This is such a unique looking creature that we thought it would be easier to identify. We believe it is some larval or pupal stage of an insect. We wish your image had better details as we cannot even begin to try to classify this creature. Our best guess at this time is that this is the Pupa of a Tortoise Beetle from the subfamily Cassidinae based on its resemblance to this image, also from Costa Rica, posted on FlickR. It is obvious that they are not the same species, but there are similarities. Not wanting to give up, we continued to search and we found an image on FlickR from Mexico that is identified as the larva and adult Wild Olive Tortoise Beetle, but alas, there is no scientific name. The poster, Seth Patterson, writes: “one of most common here in the Lower Rio Grande Valley is a larger species that feeds on our Mexican Wild Olive trees. They are called the Wild Olive Tortoise Beetle. My first encounter with this species left me truly smitten. I actually didn’t first encounter the ‘beetle’ (adult stage) but rather the larval stage. Their spiny, robust bodies are incredibly similar in appearance to the prehistoric trilobites. When threatened, the larvae raise their forked tails in an imposing display. Of course, they are all show and completely harmless to humans.” The leaves in your image do resemble the leaves of an olive, so we continued to search. The Texas Entomology page identifies the Wild Olive Tortoise Beetle as Physonota alutacea, but there is no image of the pupa. This image of a pupa of the Wild Olive Tortoise Beetle on BugGuide looks like an exact match to your critter.
Hi, you are really, really great !!!
Thank you so much for check it out my image, Sincerely I didn´t expected for an answer. Unfortunally, I shot just two photos of that bug, which was been sent to you, here you can find them in more high resolution : Physonota Alutacea.
Thank you for your quick response.

Could it possibly be Stolas areolata? A reference picture… http://www.flickr.com/photos/pararu2008/3151405985/in/pool-bbe/ and http://www.biol.uni.wroc.pl/cassidae/katalog%20internetowy/stolasareolatafig.htm Also a link to a wonderful site with hundreds of pictures of tortoise beetles… http://www.biol.uni.wroc.pl/cassidae/katalog%20internetowy/listofphotos_A.htm
It takes quite a bit of time to go through the photos due to having to click a separate link for every photo; but they have an amazing archive in my opinion.
The exact species ID might not be possible without examination of the specimen, but Stolas areolata looks very close and Stolas is most surely the correct genus.
I confirm the identity of this beetle as Notosacantha dorsalis (originally in the genus Hoplionota). All known information on this species (as well as a photo) has been reviewed by me in the papers 79 and 252 available as free pdf files from http://www.calodema.com
Thank you, Trevor
hi wildboy, I couldnt help but notice your nice picture of what goes by name golden tortoise beetle binominal name (Aspidimorph furcata). check it out on search on google. I live in thailand and take pics of these beautiful beetles all the time. its said they can change color and have a dull phase. there are also tortoise beetles that are metallic green and black, otherwise similiar but perhaps smaller.
sorry, incorrect on spelling binominal name spelling correction is=(Aspidmorpha furcata) on golden tortoise beetle.
I took some pictures of Tortoise beetle at my yard :

One of them is a Cassida circumdata.
we had these on out potato plant vine
They are also called Sweet Potato Tortoise Beetles.
lovely!
Very cool!
catch it! it’s worth 150 points :p
I, too, have found this beautiful gold beetle on my sweet potato plant. Are they “good ” to have around as the ladybug is? Or will they turn into an unwanted bug?
Bonnie
They are Leaf Beetles and their larvae are gregarious and they feed on leaves.

Physonota alutacea, the most common Physonota species distributes from Taxas to the south part of the Central America.
Thanks for the information. We will look for some links.
It is Stolas stevensi. I´m a park ranger in Ilha Grande, Brazil and I saw it more than once. I have pictures of it too.
Thanks so much for writing in with an identification. We will attempt to find a link to include with the posting. You may submit your images using the Ask What’s That Bug? link on our site.
I have a very, very helpful tip… don’t get your fingers that close to a spider unless you know what kind it is:)
Chrysomelinae to me. Looks close to Paropsisterna:

we found this gold bug at our premises
is this normal to find in South Africa
Strange the people I told here also confirm this is not usual in SA

I found one of those on my bathroom wall , I live in North Carolina, Claremont it’s so pretty, I put in the area i live in because i was kinda wandering the range of the species.
Golden Tortoise Beetles are found across North America, according to BugGuide.
Thank you very much…maybe it is…can you please tell me how long does it take them to grow adult?
Generally, the life cycle of most Leaf Beetles is a single year, so the larvae would mature in less than that time, possibly as little as four to six weeks.
Hi Suman, do you have plant-eating ladybirds (Epilachnini) in your area? This looks like the larva of Epilachnini in South Africa that I find eating Solanum species. The adults are not glossy but covered in very fine fuzz/hairs.
Hello beetle sleuths.
This beetle is from the genus Paropsisterna, probably P. gloriosa.
The taxon Chrysophtharta was recently synonymized into genus Paropsisterna (Reid 2006) adding 55 species to the now 122. Chrysophtharta is an unofficial subgenus, including those that fade after death.
I am reluctant to determine your beetle because it is seems rather blurred.
It looks close to Paropsisterna gloriosa which normally has brighter and more distinctly bounded colors. https://sites.google.com/site/paropsisternapages/paropsis-sp
A very closely related beetle Paropsisterna annularis is observed to occur in a ‘faded’ form which might be an aberration or a teneral or overwintering form, I do not know but suspect the former. I have seen examples of P. gloriosa that also occur as pale form and I suspect your photo is more accurate and less blurry than it seems. Compare the pale and normal forms here https://sites.google.com/site/paropsisternapages/paropsisterna-annularis
This is a very tricky group and I have derived these ID ‘s from Blackburn’s 1899 descriptions.
Thanks for your wonderful analysis.

I saw one of these gold ladybugs at work today in Harborcreek, Pa. I’m glad I took a picture of it before it flew away. It was very awesome to see it!
I just saw my first Glittering Gold Ladybug here in my one acre Native Vine Pine wood Jungle! It amazed me how brilliant the glittering was! Gods’ Creation is Amazing!
Cassida circumdata: Pic 1.
Pic 2 is Chiridopsis scalaris.
cheers!
Thanks for the ID Boris.

I have to weaken the ID of the first:
It may rather be Cassida catenata (Boheman, 1855) – a very similar species, widespread in the Malaian region. Though both are really variable in pattern, it remains a guess, which one it really is.

Is there a site or store that sells these types of beetles today?
I found a bright gold beetle on our ornamental sweet potato vine in N.W. Arkansas. I placed it in my hand to see if it was alive. It didn’t look as if it were so I placed it on the dirt in the planter. The next day it was back on the same leaf I originally found it on.
Found a gold bug the size of a lady bug. How can I send a picture?
Are they supposed to be here in North America too? I have pics of one that was on my car window here in Michigan.
Many Tortoise Beetles are found in North America.
May be Chrysomelinae.

It seems that it is indeed a ladybug, Cycloneda devestita.
Thanks for the correction Cesar. We found an image on the Coccinellidae de Paraguay site.
Hi again,
It seems that it is indeed a ladybug, Cycloneda devestita.
How do I get rid of these Gold Tortoiseshell Beetle? They are chewing holes in my sweet potato vines.
This looks similar to one that I photographed east of Sant Cruz, Alta Verapaz, Guatemala. I haven’t identified it yet, but I suspect it is a Physonota sp.
Hemisphaerota sp.: https://bugguide.net/node/view/8908/bgpage probably H. palmarum: http://coleoptera-neotropical.org/paginas/2_PAISES/Hisp/Chrysomelidae/Chrysomeloidea-hispaniola.html
Thanks much Cesar.
Just found some larvae & 1 adult Argus Tortoise Beetle in my yard after a hard rain last night, in the Oklahoma Panhandle. I’d post pics but there is no option.
I just seen and shiny orangish bug the size of a ladybug on my morning glory vines. I’ve never seen one like it in South Texas. Is it the same as this beetle or is it an Asian ladybug like Google told me?
Looks like Acromis spinifex
I saw a golden tortoise beetle on a pole, yesterday, at Carrick Shopping Center in Pittsburgh, Pennsylvania.
I was just cleaning out my morning Glories and believe I found one of these on the seeds I was collecting. Are they very tiny? Just a bit larger than the seeds themselves? It looked like it had white eyes. I am in Indianapolis
