It is one that takes place with full glitter. This is the courtship behaviour of some of the most interesting creatures on earth, the nocturnal fireflies and glow-worms. Belonging to the families, Lampyridae and Elateridae , they are neither flies nor worms, but beetles. Found mostly in the tropics, they possess the ability to produce light by luminescence, so no energy is lost through heat.
All species have shapeless bodies with soft dull-brown exteriors.
In many Lampyridae species, the female is wingless. Adults have an average life span of 30 days. Therefore, they devote their short lives to finding partners to mate with The luminescent organs, located on the underside of the abdomen, are derivatives of the fat body. These consist of three layers. The innermost layer has cells that are packed with microscopic crystal of uric-acid salt to act as reflectors.
