Bark Scorpions (Lychas scutilus), family Buthidae, see with white light (above) and with a black light (below), SIngapore
Black lights are very useful for finding scorpions at night, because they fluoresce under such light. (Often fluorescing shades of blue or green).
They should, however, not be exposed to them long term, as the exoskeleton can be damaged from prolonged exposure.
