I apologize for posting this out-of-focus picture of a dead scorpion on the RV drive, but the lighting conditions weren’t too good to avoid a slight camera motion that blurred the image. At any rate, I just wanted to show how these little beasties show up if you put ultraviolet light (a.k.a. black light) on them.

A while back, we bought little hand held flash lights with UV LEDs just for the purpose of detecting scorpions. Our little Miniature Pinscher, Cabela, found this nasty little bug on the patio (thank goodness it was already dead) and I found a couple of them (also dead) in the garage the other night using the UV flashlight.
