I was hiking last weekend near a small stream and saw this heart shaped leaf. Upon looking closer, I noticed a very small blue bug that appeared to look like the monster in Little Shop of Horrors. It had a large mouth and spiky barbs surrounding its body. Any thoughts?

Tortoise Beetle Larva

Tortoise Beetle Larva

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.
Thanks,
Howard

Now please give me name. Thank you very much.

Dear Suman,
Our initial web search did not produce any matching images while searching with the key word Nepal, but we believe, based on the similarity in appearance to other species from other locales that we have identified, that this is the larva of a Tortoise Beetle in the tribe Cassidini.  Here is an image of a North American individual from BugGuide.  The larvae of Tortoise Beetles are often quite spiny, they feed on leaves and they are often very host specific.  Perhaps one of our readers will be able to provide some more specific information.

Dear Sir
My friends found this beetle in their house today (25/07/15). They can’t find an exact match in any book…could you help satisfy our curiousity?

Leaf Beetle

Leaf Beetle

Dear J.,
We found a pretty close match to your Leaf Beetle online, but we are not certain if the black thoracic region on your individual is accurate, or a result of the lighting, because all the images of
Lochmaea capreae that we found have lighter coloration, including the ones on Diptera Info and on Insects of Scotland where the thorax is described as:  “a slightly yellowish pronotum with three uneven black markings on it.”  So, we are not certain if we have correctly identified your beetle to the species level, but we are confident it is a Leaf Beetle in the family Chrysomelidae.

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

Wild Olive Tortoise Beetle Pupa

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.

I’m a biology technician at a 6th form school and have inherited a collection of animals/ plants/ insects that I’m slowly trying to identify. So far I have 1 in the insect section left to identify. Unfortunately I can’t give any details about where it came from or what it’s habits are like as they are all dead! All I know is they are currently in England and I believe are likely to have been caught here. I’m not even 100% certain they’re real, beetles are not my forte

Leaf Beetle: Desmonota variolosa

Dear Hannah,
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!

Hi, I found lots of these climbing on my apple tree. There was also a type of white fungus around which some of them congregated – this possibly contains eggs?
I don’t know if they are bad for the tree or not. They measure approx. 1cm, but some are slightly smaller. They have 6 legs but the back part of their body looks like a caterpillar.
I hope you can help.

Lady Beetle Larvae eat Hemipterans

Lady Beetle Larvae eat Hemipterans

Dear Barbara,
While there is a pest problem on your apple tree, nature seems to be controlling the situation.  What you have mistaken for fungus or eggs is actually a type of Hemipteran, possibly a Woolly Aphid which you can read about on the Royal Horticultural Society site.  The crawling insects are the larvae of Lady Beetles, and they are feeding on the Hemipterans.   The bad news here is that the Lady Beetle Larva is an Asian Lady Beetle Larva, a nonnative species, and it is believed that the proliferation of nonnative Asian Lady Beetles in North America is contributing to the decline in numbers of native species.

Hi Daniel,
Thank you so much for the information – so it is good news and bad news!
Since posting, many of the larva have now attached their back ends to the tree bark and are hanging upside down, obviously in preparation for their next stage of development.  Also, there is now very little evidence of the ‘white fluff’ so they have probably done their job.  Unfortunately, many of the leaves on the tree are not looking very healthy but I am loathe to spray anything and just let nature take its course so I can review the tree in the autumn (it is past its prime anyway).
Thank you again for your help.
Regards
Barbara
