This little beetle is actually a Tortoise Beetle and the plant damage is from the beetle. This is most likely a 13-spotted Tortoiseshell Beetle (there are two species in your area). They are a pest of sweet potato plants. I can't find a photo that looks exactly like yours but very similar: http://keys.lucidcentral.org/keys/sweetp...

Nice one. Are the black spots on the leaves a fungus or something like that?
