(Chrysopidae) This family is spread in all major regions of the world and includes more than 1,300 crepuscular or nocturnal species. Adults are of medium size, and their wings are often transparent and glitteringly colourful. The colour of their bodies is usually greenish to brownish. Many species have eyes that shine with gold colours, a characteristic that is considered the main reason for the name of this family. In many species, communication is performed by vibrations, especially during the mating period. While this family is mainly predatory, several groups of species feed only on aphids. Many species of this family like the tree environments. Larvae are predators and actively look for their moving preys. For their camouflage, larvae cover themselves with the leftover of their preys using long bristles on their body. Some species of this family are bred for using them in the biological control of mite pests in agriculture.
