Epicauta hirticornis are slender beetles with black wing covers, red heads and striped black-and-white abdomens; the head is clearly set apart from the thorax and the abdomen tip sticks out beyond the wing covers. They gather in groups and the females lay yellow eggs in soil, where the larvae later hunt grasshopper eggs. Like other blister beetles, they produce cantharidin, a chemical that irritates skin and can burn the lining of the gut and urinary tract if swallowed.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
