Since this critter was long and thin I figured I'd just composite it with itself, different angles, and add some close-up portraits. I've never seen a bristletail before, but when I saw it I thought it looked different enough from a silverfish that it might be something else - backed out from the bristletail section here and, sure enough, it looks a whole lot like the bristletail images. I spotted it clinging to the outside wall of a bathroom in a park. There were others on the walls inside.
