I noticed several of these guys outside, all in a vertical position clinging to a wall. I didn't come to them too closely, but my immediate reaction was that they are scorpions.
I thought that maybe it's a curled-up scorpion, or maybe there's some kind of particular scorpion that is this circular in shape? These are probably silly conclusions, but I'm not an expert in this field. I would really appreciate the insight of a professional!
thanks very much.
