Drepanacra binocula

Australian variable lacewings are typically found in colonies of the insects they prey on.^[11] It has been seen feeding on a variety of hosts, including Psyllidae, spruce aphids, pine aphids, whiteflies, Eriosoma lanigerum and Trioza vitreoradiata.^[12][11] Drepanacra binocula can be identified by the distinctive shape and brown colour of its wings.^[11]

The species has been established in New Zealand since at least 1930.^[12] Drepanacra binocula is host to a parasitic wasp, the Lacewing Parasitoid Wasp Anacharis zealandica.^[11]

The early stages of D. binocula are egg, larva, and pupa before they emerge as adults. The eggs are pale grey when laid but darken to grey/brown before hatching. As they hatch, they use a blade-like bodily structure called an oviruptor to pierce the egg. After hatching, they go through three larval stages until they enter a cocoon where they mature until they reach adulthood.^[13]
