Adult Lesser Hornet Hoverflies are 15 to 17 mm long and have three yellow bands on a black abdomen, with the first two bands often broken by a black wedge. They are seen from early July to early September visiting flowers such as yarrow, dill, heather, thistles and Buddleja, and females lay eggs inside social wasp and hornet nests where the larvae parasitise wasp brood.

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.
