Firefly (or Net-Winged Beetle) Larva

Dear Matt,
This is a Beetle Larva in one of two families.  Our first choice is a Firefly Larva in the family Lampyridae, but we would not discount that it might be a Net-Winged Beetle Larva in the family Lycidae.  Larvae from the two families are difficult to differentiate from one another.

Dear J,
This is neither a moth nor a Cockroach, but it is a Beetle.  It is a Firefly.

Your letter to the bugman:  I found this at night, glowing on the ground next to my home.  I live in a rural area.  I have not seen anything wit this glow pattern before or since. It was found June 2 at 10 pm.  I returned to where I found it after photographing it. I am attaching a picture with the lights on so you can see the caterpillar and one with the lights off so you can see its glow.

Glowworm

Dear Yvonne,
This is a Glowworm, the larva of a Beetle in the family Phengodidae, not a Caterpillar.  Here is a similar looking image from BugGuide that is also from Iowa.

Your letter to the bugman: 
I saw this beetle on a moss-covered rock while birding. It looks like a Trilobite Beetle. I would like to know the species.

Firefly Larva, we believe

Dear Leons,
This is a Beetle larva, which might make exact identification difficult if not impossible.  We believe this is a Firefly larva, but we would not rule out that it might be a Net-Winged Beetle larva.  According to Eric Eaton, if you watch it eat a snail or slug, it is definitely a Firefly larva.

Dear Caitlin,
This harmless male Glowworm is not the cause of your bites, bumps nor rashes.
