The Virginian tiger moth is a white moth with a darker abdomen and lacks the dark eyes of its close cousin. It lives across northern America, especially in the western regions, and its caterpillars are common in yards and gardens. The larvae eat many low-growing plants and can skeletonize leaves, sometimes harming crops in late summer.

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.
