They glow under black light for the same reason that cat urine or black light paint glows under black light: fluorescence. Their exoskeletons probably contain a protein or some other substance that is fluorescent. Fluorescence is a luminescence that is mostly found as an optical phenomenon in cold bodies, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength.
