Scientists think that scorpions may have evolved this feature to be able to detect moonlight, which does give off ultraviolet radiation. This would help a scorpion let it know that it can be seen (via the moonlight) by predators and look for shelter.

Another line of reasoning suggests that scorpions glow to convert the dim UV light from the moon and the stars into the colorur that they see best – blue-green. This could explain why scorpion eyes are so exquisitely sensitive, to the point where they can detect the faint glow of starlight against the background of the night sky. They amplify those faint signals by turning their entire bodies into light collectors.
