I have no idea what this is
I found these on my husband’s Hot Pepper plants. They are about the size of a pea. They seem to always run in pairs. At least two on every leaf. There bodies are very hard. If you touch them the will tuck their legs and antlers in and laid kind of flat. I have never seen anything like them in all the years we have been growing these pepper plants. Here are a couple of pics. Thanks for your help.
This is a Clavate Tortoise Beetle in the genus Plagiometriona. They feed on pepper plants and other members of the tomato family Solanaceae.
