Males are green with blue on the last two abdominal segments, while females can be orange-red, olive green, or look like males. They live around ponds, lakes, marshes and slow streams with plants and sunlight, and their nymphs can even be found in brackish or sulphurous water. They are beneficial insects that eat mosquitoes and other small insects and do not harm humans.

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.
