Description
The kawakawa looper moth grows about 10 to 15 millimetres long and has a wingspan between 30 and 55 millimetres. Kawakawa looper moths vary in colour from a mottled yellow-brown to brown-black. They usually have a spot on each forewing.
Caterpillars can be 30 to 40 millimetres long and are mainly green or brown. A new caterpillar is green in colour and has dark or white stripes the length of its body. They position themselves on the leaf veins and lay as flat as possible to camouflage themselves. Caterpillars can drop from plants and hang by a silk thread.

Symptoms and damage
Caterpillars feed on young leaves usually making holes in the edges and centre. The leaf damage is mainly aesthetic and people harvesting kawakawa for rongoā would use the leaves with holes.
Prevention and control tips
In the nursery you may consider treating with chemical insecticide or product for caterpillars to prevent leaf damage if plants became unsaleable. In most circumstances treatment would not be required.
