Lacewing Neuropterans are fragile, soft-bodied insects, and have long segmented antennae. They may range in body size from 2 or 3 millimeters to 60 or 70 millimeters. Most Neuropteran adults and immatures have chewing mouth parts, but some species have sucking mouth parts. Neuroptera undergo holometabolous development, passing through egg, larval, pupal and adult stages in their life cycle. Neuropteran insects have two pairs of membranous wings which are held roof-like over the body when at rest, as you see in this predatory lacewing (Chrysopa species). Both pairs of wings have a lacework of veins and cross veins, hence the name lacewing. Larval lacewings are highly predaceous on aphids.
