Drepanacra binocula, known as the Australian variable lacewing, is a species of brown lacewing in the family Hemerobiidae,[1] [2] found across Australia and New Zealand, including Lord Howe Island, Norfolk Island and the Kermadec Islands.
Australian variable lacewings are typically found in colonies of the insects they prey on.[3] It has been seen feeding on a variety of hosts, including Psyllidae, spruce aphids, pine aphids, whiteflies, Eriosoma lanigerum and Trioza vitreoradiata.[3] Drepanacra binocula can be identified by the distinctive shape and brown colour of its wings.[3]
The species has been established in New Zealand since at least 1930. Drepanacra binocula is host to a parasitic wasp, the Lacewing Parasitoid Wasp Anacharis zealandica.[3]
