North East US: This insect flies proficiently. That 'carapace' (it is hard) opens up somehow to allow flight. Two large butterfly-positioned antennae. With their legs pulled in they are _flat_ under the carapace. I only see them on my potato plants. But am not convinced they're actually eating the leaves -- though something is (as evidenced in the jpg)
anybody shed any light on who they are and who is eating the leaves?
thanks
