oh fucking fuck those are wind scorpions i think. my roommate had one between her legs once after putting a skirt on that had been on the ground for a few days/weeks and BOY did she go ape shit.I would too!
I found one of those twice in the 3 years we have been here in Apple Valley, CA. Also, recently found one at the front porch, up above the awning! Yike......horrible. I sprayed it and of course it died and I put it in a tissue to ask others what it was and finally I looked it up on the computer on this site and found out more information about it.
