The Flower Elf firefly (Pyropyga minuta) is a tiny black beetle about 3 to 7 mm long, with a pale yellow pronotum marked by a dark rectangular bar. Adults are active in daylight during June and July, often found on leaves and flowers in gardens, yards, open woodlands and similar open areas across the southern United States, Mexico, Guatemala and Honduras. The larvae live underground and glow bioluminescently, while the adults lack lanterns and do not flash.

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.
