Grevillea Looper - Oenochroma vinaria

Grevillea looper is the larva of a common native moth that occurs across eastern and southern Australia, including south-west Western Australia.

Lavae chew the leaves of grevillea, hakea and occasionally bankisia plants. The larvae are greenish-brown, smooth-skinned caterpillars up to 80mm long covered in white spots.




Oenochroma vinaria - green form

The general wing colour of the adult moths varies, some are pink and others brown. The body varies from pink to brown also. The moths all have a brown or yellow line across the upper surface of each wing and when at rest resembles a leaf. Each forewing has a recurved wingtip, and a small transparent spot surrounded by an irregular dark mark on both the upper and under surfaces.

Prevention:
Look for larvae in early summer before they do too much damage. Larvae feed at night and lie along branches during the day, making them very difficult to see.

Treatment:
Pick off and squash or feed to birds - Butcher Birds love them. Apply Dipel or pyrethrum in preference to other insecticides but follow the label carefully.

Natural Enemies:
Birds, parasitic wasps and flies.
