Glow worm (not a worm but a beetle or a fly) is the name for several different insects that glow through bioluminescence (a chemical reaction during which chemical energy is converted to light energy). There are three main families: * Lampyridae (firefly, but actually a beetle). Only the wingless females glow. Yellow-green colored light to attract males and as a warning signal to predators (they are mildly toxic).

* Phengodidae, (a beetle) found in the Americas. Yellow-green colored light to attract a mate. In this family the "railroad worms" have an extra red light at the front.

* Arachnocampa (a fly larva) found in New Zealand and Australia. Blue-green colored light to attract tiny midges into sticky snare lines for eating. The chemical reaction is very efficient with almost 100% of the energy turned into light (the best light-emitting diodes can only manage 22%).
