Adult Bagrada bugs are small, shield-shaped insects about 5 to 7 mm long with black bodies marked in white and orange. Both adults and nymphs feed on the sap of many garden plants, especially cabbage family crops, causing wilting, yellowing and stunted growth. They have spread from their native southeastern Africa to California, Arizona and Chile, where they can become abundant in fields and gardens.

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.
