Striped Blister Beetles

This is most likely a Striped Blister Beetle, Epicauta vittata, which is pictured on BugGuide, but there are also several very similar looking members of the same genus.  According to BugGuide:  “Feeds on variety of plants, especially Solanaceae (e.g., potatoes, tomatoes), also soybeans, other crops. Pigweed, Amaranthus species, not a crop plant, is also fed upon extensively.”

Nuttail’s Blister Beetle

Thanks to this BugGuide image, we are confident that this is Nuttail’s Blister Beetle, Lytta nuttalli, a species with much color variation.  According to BugGuide:  “Adults feed on legumes.”  You were lucky when you encountered this Nuttail’s Blister Beetle because physical contact with Blister Beetles should be avoided as they can secrete cantharidin, a compound known to cause blistering in human skin.

Your letter to the bugman:  Hi, my mother found this beetle a few days ago. I cannot find a similar one on the Internet. It was long with large mandibles and scarlet.:  Allnutty

Blister Beetle: Synhoria testacea

Dear Allnutty,
The first thing we have to say is WOW, that is one impressive beetle.  Interestingly, as we began our research, we found this very beetle pictured on the Travel Malawi Guide site, but alas there was no identification.  Though its appearance is not typical of the family, the antennae caused us to ponder if this might be a Blister Beetle in the family Meloidae, and there is one North American species that has a similar large head and mandibles, the Big Eared Blister Beetle,
Cissites auriculata, which is pictured on BugGuide, so we started our more thorough search with the subfamily Nemognathinae.  That led us to the Researchgate and Meloidae of Namibia where Plate #6 pictures Synhoria testacea.  We verified that identification on iNaturalist where there are several wonderful images.  It is also pictured on What Species?

Spotted Blister Beetle

Dear Lisa,
We are quite confident that we have identified your Blister Beetle as a Spotted Blister Beetle,
Epicauta maculata, thanks to images posted to BugGuide.  The larvae of Spotted Blister Beetles feed on Grasshopper eggs, but adults are plant feeders as you have experienced.

Blister Beetle

Dear Dr. Pachanga,
This is not a Rove Beetle, but rather a Blister Beetle, and its red eyes are startling.  We wish your close-up had more clear details.  We believe we have correctly identified it as Berberomeloe insignis thanks to images by Peter Greenwood on FlickR here and again here on FlickR.
