Claim When placed under ultraviolet light, scorpions fluoresce to glow a blue-green color. Fact CheckScorpions are creepy and they’re kooky, mysterious and spooky, and come with an evolutionary ooky — that is, the ability to glow under UV (ultraviolet) light. For background, most of us know UV light as its most common form: sunshine. Other species of insects also glow under UV light, including species of spiders, lightning bugs, and centipedes. Most scientists agree that the ability of scorpions to glow under ultraviolet light allows them to detect where UV light is, and isn’t, thus giving them the ability to determine when they are covered and hidden from potential predators.
