I saw this thing on the driveway, picked him up and put him on the hood of my Plymouth Laser. Most of the shots were garbage. I just couldn't get anything sharp. If I used no magnifying filters, the focusing distance was too great for me to get the focus right. With the filters, I could get close and determine where the focus was, but I'd loose sharpness. It was a frustrating weekend...
As for what it is... It looks like it might be a glow worm. Too bad I didn't know before. I woulda caught him and taken him somewhere dark to see him glow...
