Look, but don't touch!

This is a black blister beetle (Genus Epicauta).  Their larvae eat grasshopper eggs but the adults mostly hang out on flowers and eat nectar and pollen.

Blister beetles (Family: Meloidae) are pretty infamous for their ability to defend themselves with a  poisonous chemical called cantharadin. They will secrete the toxin if you try to eat them or handle them too roughly, so be careful if you see one of these!
