Males have a long curved horn on the head, while females lack horns. It lives in decaying wood, the larvae feed on woody debris, and the whole life cycle takes 2 to 4 years, with adults appearing from late March to May and being active in June and July.

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.
