The bee moth is a European moth whose females lay up to a hundred eggs in bumblebee and wasp nests, and the larvae feed on the nest’s eggs, larvae, pupae, pollen, honey and waste. Adults have a wingspan of 18 to 40 mm, reddish-brown to dark-green forewings, and females show a dark spot on each forewing; they fly from June to August and emerge in early summer. The species is considered a pest because its larvae can severely damage commercial bee hives.

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.
