Last week I had a chance to chat with Nate Butkus, 10-year old host of The Show About Science. We decided to start a FireBeetle* movement, and I geeked out about the gory side.
Meanwhile, enjoy these visuals from KQED’s Deep Look!
*Unfortunately, the name “fire beetle” has already been snagged by an Australian beetle (Merimna atrata) whose larvae develop in freshly burnt wood.
Every June, fireflies light up the Smoky Mountains with their exuberant courtship displays – sure, it all seems very romantic. But a few years ago I spent some weeks with colleagues studying the predators that take advantage of these dense breeding aggregations. We knew that certain insectivores â like birds and lizards â avoid eating fireflies because they’re toxic. So we didn’t expect to find many predators enjoying this luminous feast. Little did we realize how gore-filled that summer would turn out to be!*
Each autumn the world seems aglow with foliage and jack-o-lanterns. But they’re not the only glowing things lighting up this season. Fall is also a great time to spot the crawling, glow-in-the-dark stage that all juvenile fireflies pass through.

Hatched from eggs laid during summer months, these firefly larvae can now be seen crawling along roadsides or wooded paths, glowing dimly from two tiny lanterns.   Photuris and Pyractomena larvae are the two types seen most often in the U.S. But one reader in Portland, Oregon even spotted the much rarer Douglas fir glow-worm, Pterotus, along a path in Mt. Tabor Park. Continue reading
