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.
How you want your letter signed: Yvonne
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.
