Just in case anyone wanted to know why scorpions fluoresce. Proteins in their exoskeletons convert the UV into visible light with a blue hue (although the little buggers around here fluoresce green). Scorpions will also fluoresce under moon light due to the UV it reflects. I'll have to check this one out as I don't think I've seen them fluorescing from just the moon.
Anyway just some fun but probably useless facts to most of You.
