Slug Caterpillar? - Cassidinae beetle larvae
Knox, Albany County, New York, USA
July 12, 2020
Size: ~5mm TL
Two of these, each feeding on a separate leaf of Hedge Bindweed, Calystegia sepium. It reared up into this posture when the camera got close. Looks like one of the stinging slug caterpillars, carrying a shed skin. Do any have black early instars, and carry a shed skin? Do any beetle larvae have these stinging spines?

Sorry - actually the photos are of the same individual. I observed the two individuals on the same plant that to me looked like the same species, but I only uploaded photographs of one of the individuals (I've learned to do this through hard experience.)

Do you know, are the spines venomous?
Two days after these photos I observed a tiny wasp crawling around on the larva. It seemed to be having a hard time getting past the fecal shield & spines, i.e., they were functioning as intended.
