Feces Carrying Tortoise Beetle Larva

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.

My son found this boldly patterned beetle that appeared to be brushed with gold dust on a beech sapling that was covered in fat grubs reminiscent of potato beetle larvae that were eating the leaves. I don’t know if the larvae had anything to do with the beetle itself but I thought it might be worth mentioning even though I didn’t get a picture of them. These pictures were taken at the D.A.R. State Forest on June 28, 2017 in Ashfield, Massachusetts. I scoured all my insect field guides and guides to New England wildlife to no avail. I’ve asked amateur nature buffs and no one has been able to identify this little beauty. My brother suggested asking “What’s That Bug.”
Thank you

Leaf Beetle

Dear N. Gerlach,
This is a Leaf Beetle in the genus
Calligrapha, and many species in the genus look very similar.  Your individual appears to be Calligrapha rowena based on this BugGuide image.  According to BugGuide it feeds:  “on Cornus (dogwood).”

Thank you so much!  I can’t wait to share this identification with my family.
