Spotted Cucumber Beetle

Spotted Cucumber Beetle

Dear CC,
We believe that if you look at images posted to BugGuide, you will agree that this is a Spotted Cucumber Beetle,
Diabrotica undecimpunctata.  BugGuide remarks:  “Considered a major pest of many field crops including cucumbers and other squashes, corn, soy. Beetles also transmit crop diseases such as bacterial wilt. Adults also reported damaging to garden plants including hibiscus, roses.”

Dear Bugman,
I ran into this creature while inspecting my swamp milkweed for monarch caterpillars. I found ver 10 caterpillars as well as this gray and sort of shiny creature. It has 5 black dots on each side and I think I see 6 legs but really small. its about the size of a ladybug. Found it on underside of Swamp. Milkweed leaf toward top of stem. I cannot tell where to begin to find out what this little guy or gal is and if he/she means harm to my milkweed or my monarch caterpillars.
Thanks so much!

Swamp Milkweed Beetle Larva

Swamp Milkweed Leaf Beetle Larva

Dear Fran,
This is the larva of a Swamp Milkweed Leaf Beetle,
Labidomera clivicollis, and we identified it on BugGuide based on this image.  According to BugGuide:  “Larvae and adults cut several side-veins of a milkweed leaf prior to feeding, to reduce the sticky latex that would otherwise be produced at their feeding sites.”  So, the larvae and adults of the Swamp Milkweed Leaf Beetle share the same food source as the Monarch Butterfly, and unless the beetles are so populous that they defoliate the plants, they are not a threat to either the milkweed or the Monarch caterpillars.

Thanks you so much.  A few folks had thought it might be a false Potato Bug larvae??? Since I found it on a swamp milkweed leaf, a Swamp Milkweed Leaf Beetle makes sense!
Thanks do much!

Hi! I’m a nature illustrator and have created a sculpture of a Tortoise beetle, but I cannot find the scientific name of the beetle. I hope that you can help me find it so that I can accurately label the artwork! I have attached an image of the sculpture.
Thank you so much for your help!!

Illustration of a Tortoise Beetle from Guyana

Illustration of a Tortoise Beetle from Guyana

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!
Zebith

What is this lovely little guy? He looks like he has dropped in from outer space or a 70s disco party. Will he be staying for dinner? If so, which of my pants will be served up?

OK, see this beautiful gold ladybug and got a great photo of it before it flew away! Looked it up online and everyone that talkes about a “gold ladybug” says it’s a tortoise beetle, but the pictures of them look nothing like the beauty that landed on me. So, if not a tortoise beetle what is it? Thanks !!

Leaf Beetle: Common Willow Calligrapha

Leaf Beetle: Common Willow Calligrapha

Dear April,
This is neither a Lady Beetle nor a Tortoise Beetle, but it is a Leaf Beetle in the family Chrysomelidae, and that is the same family as the Tortoise Beetles.  We believe your Leaf Beetle is a Common Willow Calligrapha,
Calligrapha multipunctata, based on images posted to BugGuide.

Thank you!!! I looked it up and it says it’s found in eastern united States? So it must have been lost or the info is not up to date I read( not on your site)! Lol thanks again for your  time!!

Though BugGuide does not list any Nebraska sightings, there are sightings in nearby Colorado, New Mexico and Texas as well as point farther west.  Additionally there are other similar looking species in the same genus.

I occasionally find these in my kitchen they kind of jump and I believe they have wings like ladybugs but I haven’t seen them fly just jump…

Northern Plantain Flea Beetle

Northern Plantain Flea Beetle

Dear Concerned Mama,
Thank you for including a pack of Newport cigarettes for scale, and in our opinion, that pack poses a far greater health threat to all involved than this Flea Beetle does.  We believe we have correctly identified it on BugGuide as the Northern Plantain Flea Beetle,
Dibolia borealis, and based on the size relationship to the pack of cigarettes, the stated 3mm size seems about correct.  According to BugGuide, they feed on:  “Plantago spp. (Plantaginaceae)” and “Larvae are leaf miners of plantains. ”  According to The Herbal Encyclopedia:  “The plant is indigenous to the Mediterranean region and western Asia; but it now grows worldwide … .  To many areas, it is considered a weed.  The herb is an annual that grows to about sixteen inches in height, producing narrow leaves and clusters of tiny whitish-brown flowers.”  Plantain grows in many fields and open areas in the eastern part of North America.  Perhaps you have some plantain near your kitchen which is causing the Flea Beetles to accidentally enter your home.
