Hi there,
I found this really cool looking insect while hiking in northern Michigan and I’ve never seen anything like it! It looks like a larvae of some sort and is black on the top and pink underneath. It was just under the top layer of a rotten log and was about an inch (3 cm) long. If you can ID it that would be awesome!

Firefly Larva

Firefly Larva

Dear M,
This is the larva of a Firefly and you can verify our identification by comparing your image to this BugGuide image.  According to BugGuide:  “Larvae prey on small animals, including snails” and “larvae mostly in damp situations.”

Found several of these after dark on a drizzly day. They were in leaf litter near the Little Buffalo river in the Ozark Mountians of Arkansas on November 9. Temperature was about 60F. Rain was the first precipitation in over three weeks. They glowed on and off like fire flies but with a slower rythm thatn the fliers usually do. Fire fly larva or Glowworm?
Thanks

This is definitely a Firefly LarvaGlowworms look quite different.  We wish you were able to submit an image showing the bioluminescence.

I will give it a try!  Thanks for the feedback.

I’ve never seen a firefly like this one before. It’s small, about 1 centimeter long, and was attracted to my porchlight. It’s capable of lighting up a deep green color, but reluctant to do so and the flash isn’t very bright. I couldn’t find a match on bugguide.

Dear Sam,
Alas, though we are not able to identify your Firefly past the family level, we will post your three wonderful images and perhaps one of our readers more skilled at identifying Lampyridae than we are will be able to provide more conclusive information.

Update:  Thanks to a comment from Gene St. Denis, we are linking to the genus Photinus on BugGuide.

Male Glowworm

Male Western Banded Glowworm

Dear Carol,
This is an adult male Glowworm Beetle probably the Western Banded Glowworm,
Zarhipis integripennis, which is pictured on BugGuide.  While male Fireflies that flash with bioluminescence as adults signalling to females that respond by flashing back, male Glowworms do not light up and only  larviform female Glowworms glow in the dark to attract a mate.

This insect seemed to curl the tail to propel itself forward. It was only 2.5 cm long. We found it on the front porch in southern Indiana at the end of March.
