The Small White butterfly has a wingspan of about 32 to 47 mm and is creamy white with small black dots and black tips on the forewings; females show two extra black spots on the forewings. It lives in open areas such as towns and valley bottoms across Europe, Asia and North Africa, avoiding deserts unless irrigated, and its caterpillars feed on cabbage-family crops. Eggs are laid on wild and cultivated brassicas, with two flight periods in Britain (April-May, July-August) and continuous broods in North America.

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.
