Lacewings (order Neuroptera) are important predators in a large number of agricultural systems. Lacewings have complete metamorphosis, with egg, larval, pupal and adult stages. Adults are soft-bodied with large, transparent, intricately veined wings. Larvae are alligator-like with long, sickle-shaped mouthparts extending forward from the head. All lacewing larvae are predaceous; adults may be predaceous or feed on nectar and pollen.
