They live in high densities near rivers, ponds, streams and agricultural areas across eastern North America, including New England, Georgia and regions west of the Rockies. Females carry large egg sacs and tend to their young for several weeks after hatching.

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.
