Your letter to the bugman: Photo taken at 9:26 pm (Atlantic time) September 27, 2017 at the brushy edge of my long rural driveway. On a number of nights, I saw a faint glow in several places on the ground as I was walking. When I investigated, I saw this character moving slowly and glowing at the edges of its sides. Never saw more than one at a time in any given spot, but some weren’t far from each other. I think it was approx 5-7cm long.
How you want your letter signed: Andrew
This sure looks to us like the larva of a Firefly, and since you did observe it glowing, your observation does lend credence to our identification. Some Firefly larvae are capable of bioluminescence.
