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.

Your letter to the bugman:  This bug was found flying in my room and I have found over 13 total bites from one night. It then turned the entire skin into bumps/rash about 5 inches beside the bite.

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

Your letter to the bugman:  Last night I took a video of a Glowworm I found in my garage. I had mowed my lawn previous to finding it and leaf blew some clippings around. I’m assuming that’s how it ended up there. Here are some screenshots from said video. Thanks!

Glowworm Glowing

Dear Aron,
We believe your Glowworm is in the genus
Phengodes based on your location and this BugGuide image.  We were able to increase the highlights in the dark image you submitted which enhances the glow.

Your letter to the bugman:  I found a flying bug in Trenton Florida has wing’s eye lashes Orange and black with a big stinger

Male Glowworm

Dear Melissa,
This is a male Glowworm, and unlike Fireflies that have bioluminescent adults, it is generally only the larval Glowworms that give off light.  What you have described as “eye lashes” are actually antennae, and there is no stinger.  Glowworms are entirely harmless to humans.  We try to promote tolerance of the lower beasts, and it appears this Glowworm met an untimely death, so we are tagging this posting as Unnecessary Carnage.
