The twin-flagged jumping spider is a small 5-6 mm salticid with distinctive iridescent “flag” markings on its cephalothorax and male pedipalps. It lives on leaf litter, fences and walls from Mexico up to South Carolina, hunts ants with a special method and other insects by pouncing, and females guard egg sacs of about fifteen spiderlings.

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.
