RECOGNITION
Adult: Similar to Green Lacewings (Chrysopidae) but usually brown and smalle. Wings: Usually more rounded, and the membrane is covered with small hairs. Venation with two or more radial sector veins. Larva: Debris is not carried on the backs, as with the larvae of the Chrysopidae.
Body Length
6-15 mm.

BIOLOGY
Food
Predaceous on soft-bodied insects, such as aphids, mealybugs and insect eggs, as both adults and larvae.
Habitat
Woodland areas.
Active Period
Spring to fall.
Development
Eggs are laid singly or in small groups, directly to leaves (not on stalks as the Chrysopidae). There are 3 larval instars, of which the 1st is active in all species. Mature larvae spin in white cocoon in a protected area. The cocoon has two layers: the outer later is loosely threaded, and it encloses an inner, more compactly threaded lining.
Importance
Adults of some species may live for months and may consume many pest species. High reproductive capacity lends to this insect being a significant agent for biocontrol of pest insects in agriculture.
Range
Worldwide & throughout North America; more diverse in the western North America.

HABITAT
Woodland areas.
