The yellow-vested moth has a wingspan of about 12 to 14 mm and dark brown forewings with a lemon-yellow triangular patch near the base. It lives along the Atlantic Coastal Plain from southeastern Massachusetts down to central Florida and east Texas, and also up the Mississippi Valley to Missouri and Illinois. The caterpillars feed on oak leaves, especially Quercus nigra and Quercus stellata, while sheltering between two silk-joined leaves.

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.
