As I read that these can be tricky to ID, I’d appreciate your input.
I found it because it had it’s little light stuck in the air out of a grass covered bank along the side of the old Free Union United Methodist church. It was just a pin-prick of light, but bright enough to catch my eye.

Firefly Larva

Firefly Larva

Dear Phil,
This is a Firefly Larva, and we are basing that identification on the information that you provided about seeing a light.  Firefly Larvae are not easily confused with Glowworms which also bioluminescnce.  Firefly Larvae most closely resemble, hence are confused with Netwing Beetle Larvae that are not capable of emitting light.
