I was really happy to see this odd and exotic looking little larva of the Clavate tortoise beetle (the adult of which, Diane photographed for the June 2011 blog at the FWG). I have been checking the Physalis often for this sort of thing, and finally today I found two. They are minuscule, perhaps a couple of mm. That black blob on top is scat which it holds over its body for protection and camouflage!
