Explanation of Names
Named for the type genus, Chrysopa, which is named from Greek chrysos (χρυςοσ)- "gold" + ops (ω&psi)- "eye, face") with a feminine noun ending added. Presumably the type species is like many species of several genera in this family and has golden eyes.
Numbers

Identification
Soft-bodied insects with copper-colored eyes, long thread-like antennae, and lacy wings.
  
To the naked eye the wings appear hairless, but under magnification short hairs can be seen along the edges and veins. See photo and diagram of wing venation:
  
Most species are green, but some are brown, especially overwintering adults of certain species:
  
Pinned specimens turn yellowish.
Habitat
Common in grass and weeds and on the foliage of trees and shrubs.
Food
Some adults are predators, others take liquids such as honeydew, and some feed on pollen.
Life Cycle
Eggs are characteristically stalked. The eggs and egg-laying process is illustrated here:
  
Larvae are predatory, mostly on aphids, and are often called aphidlions. The larvae pupate in silken cocoons that are generally attached to the underside of leaves. See illustration:
  
Remarks
