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.

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.

I found this guy in my raised garden planter.
at night ‎on Sunday, ‎June ‎25, ‎2017, at ‏‎7:13:10 PM
he was in the area with my carrot sprouts.
I live in Norman, Oklahoma.
I kept him for a day and a half in a jar and tried to find him on the net and in my books, with no luck.
I turned him lose in my front flower beds. I was afraid if I kept him any longer he would die.
-Any help would be greatly appreciated. I have run out of resources for finding this little guy. He was about a quarter inch long.
-Thank you for your help,

Case Bearing Leaf Beetle

Dear Heather,
We are quite confident that this is a Leaf Beetle in the family Chrysomelidae, and we believe it is a Tortoise Beetle in the Tribe Cassidini, but alas, we cannot locate any images on BugGuide or in Arthur Evans’ book Beetles of Eastern North America that remotely resemble it.  We are going to contact Eric Eaton and Arthur Evans to see if they can identify your beetle.

Case Bearing Leaf Beetle

Arthur Evans responds.
I’m thinking something like this: http://bugguide.net/node/view/40716

I think it’s pinkish with three black stripes.

Leaf Beetle

Dear Buehler,
Based on this BugGuide image, we believe your Leaf Beetle might be
Calligrapha californica.  According to BugGuide:  “Host plants are Coreopsis, Bidens and Ambrosia – all composites.”  We will be post-dating your submission to go live to our site later in the month when our editorial staff is away on holiday.
