Entomology (Study of Bugs)/Strange bug with eyelashes?


Hello Jessica, my friend found a bug and she described it as being striped like a bee but has some weird eyelashes and i was wondering if you could tell me what kind of bug it is. Thank you for any help!

Hi Nolan,

The photo is of a male Glowworm Beetle (Phengodidae). The larvae and larviform females (translation: the youngsters and females look like worms) have bioluminescent organs that glow through their skin, but the males look more like your typical beetle and have the feathery "eyelashes" you mentioned. These "eyelashes" are actually antennae that are used to find females. The antennae have chemical receptors for detecting female pheromones. Thanks for the great photo.

I can answer questions about invertebrates native to California, including insects commonly found in homes. If you have an identification request, please attach a photo to your question.


I was involved in collection and identification of invertebrates for the United States Geological Survey, Biological Resources Division for six years. Also, I provided these same services intermittently for the UC Davis John Muir Institute of the Environment for many years. I have been a member of since 2009.
