Why do scorpions glow under a blacklight, and can they see UV?
Scorpions glow because their bodies fluoresce under UV light (not because they produce their own light like bioluminescent animals). People often mix up whether scorpions can detect UV with why they glow, but the practical takeaway is that UV makes them dramatically easier to find in dark rooms. This section on using UV light to spot scorpions also covers whether UV “spooks” them and why 365nm lights tend to work best.
