My friend found this on her morning glory. We aren’t sure if its a bug, larvae or egg. We have researched and although we found a few things that looked similar, we haven’t found an exact match or anyone who could help. You’re our last resort! Please help!

Leaf Beetle Larvae

Leaf Beetle Larvae

Dear Crystal,
These are Leaf Beetle Larvae in the family Chrysomelidae, and we strongly suspect that they are the larvae of Tortoise Beetles.  Several species of Tortoise Beetles including the Golden Tortoise Beetle have larvae that feed on morning glories, but your larvae look different, though similar, to the images we are able to locate on BugGuide.  Fecal matter that is carried over the back of the larva is a characteristic of many Tortoise Beetles, and it is evident in your image.  Many Tortoise Beetles are very host specific, so if you don’t mind that your morning glory leaves are being eaten, at least you don’t need to worry about the larvae spreading to other plants.

Hello there Bugman & Staff,
We work at the local Nature center here & ran across this unusual bug. We have these two shots of it. We have searched, but to no avail… now I am searching sites online. 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. ( We tag the adults & use some of them in a display for the public). We would appreciate any help or guidance identifying this small creature. We are located in Southern Minnesota.
Thank you kindly,
Jillian

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,
Jillian

This tiny critter is eating my butterfly bush. But I guess nobody will be eating him because he seems to be flying the jolly roger on his butt. False eyes?

Red Megacerus

Red Megacerus

Dear Joanne,
This lovely beetle really threw us for us for a momentary loop, because the body resembles that of a Scarab Beetle, but the antennae are decidedly un-Scarab-like.  We quickly identified this Leaf Beetle in the family Chrysomelidae as
Megacerus discoidud thanks to Beetles of Eastern North America, the new book by Arthur V. Evans.  According to BugGuide:  “This handsome species with its quadrate, red elytral maculae can hardly be mistaken for any other eastern American bruchid.”  BugGuide also indicates:  “Adults are commonly found on flowers of many plant species” and “Host plants: Calystegia spp.; Convolvulus arvensis; Ipomoea spp. Flowers of Daucus carota and Hibiscus sp.”

Hi thegnatfly,
This is the larvae of a Clavate Tortoise Beetle,
Plagiometriona clavata, and you can verify our identification on BugGuide. The attached thing is dried fecal matter.

Wow! Thank you so much! I will let my mom and others know about your site. It was found in her garden.

I found this beetle, resting on a leaf of grass after a light rain. I believe it belongs to the genus Calligrapha, but I have not been able to find any species with the same markings.

Leaf Beetle:  Calligrapha species

Ambrosia Leaf Beetle

Dear R. Avila,
At frist we agreed that this is a Leaf Beetle in the genus
Calligrapha, but like you, we are uncertain of the species.  Many species in the genus look quite similar and there is also considerable individual variation within the species.  We did a bit more research and we are relatively confident that this is an Ambrosia Leaf Beetle, Zygogramma tortuosa, and you can compare your images to those posted on BugGuide.

We saw this bug at a family picnics at the city park. I’ve been in Cleveland Ohio for 40 years and have never encountered this bug. Looks half caterpillar half insect and very alien.

Leaf Beetle Larva

Leaf Beetle Larva

Dear Matt,
This is the larva of a Leaf Beetle in the family Chrysomelidae, and knowing the food plant would tremendously help in narrowing down the possibilities.  It is very similar in structure to a Potato Beetle Larva, which causes us to believe it is closely related, and the best we can do right now is to narrow it down to the larva of a Leaf Beetle in the tribe Doryphorina.  You can compare your image to this image on BugGuide.
