Phalaenoides glycinae

Caterpillar stage

As a caterpillar, it is black with pale yellow lines that run across the body, giving it a chequered look. It has long white hairs thinly distributed over its soft skin, a light brown head capsule, red spots around the head area, and a prominent red croup. The caterpillar would usually rest on the undersurface of the leaves that it's feeding on.

The adult is a diurnal flying moth with a black wingspan of up to 5 cm having white bands on the forewings and a white outer margin on the hind wings. The abdomen is black on the top with orange bands below. The body features clumps of bright red hair on the end of the abdomen, and at the legs base. These red hairs protrude and are visible from atop.

The adult males have anterior brush organs which exude pheromones. The adults are social, feeding on nectar and would live for around 2-3 weeks. The moth can ascend as high as 25 meters or more.[1]

It is endemic to the south-eastern half of Australia, but is an invasive species in many parts of the world, including New Zealand, Canada and South Africa.

The larvae mainly feed on Parthenocissus quinquefolia, Hibbertia obtusifolia, Amyema gaudichaudii, Epilobium ciliatum, Fuchsia and Oenothera species, but mainly Vitis vinifera, hence it is considered an agricultural pest.

The Indian myna (Acridotheres tristis) was introduced into Australia in 1862 to deal with a number of insect pests including the grapevine moth. In this it was unsuccessful, and ironically the bird is now itself considered a pest in many parts of Australia.
