The Light-spotted Quaker is a moth with forewings 11 to 14 mm long and a very variable appearance, but it can be recognized by a rounded orbicular spot edged in black and an oblique reniform spot that points toward the wing’s anal angle. It lives in open, dry woodlands across a broad swath of North America from central Oregon and Idaho down through Texas to southern Mexico, and its larvae feed on a range of herbaceous plants.

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.
