The early instars of this Caterpillar are gregarious, feeding by day. Later instars are solitary. They occasionally may be seen in procession, each following the silken thread left by the one in front.
The caterpillar is dark grey and hairy. Its head capsule is white with red sides bordered with black. The true legs are red and the prolegs are orange. There is also an orange lateral line along each side, with a row of orange spots above it. The body is speckled with yellow dots. A pair of long white hairs project diagonally forward from the thorax.
The caterpillar feeds on various species in MYRTACEAE, including :
The caterpillars grow to a length of about 3 cms. When the caterpillar is mature, it crawls under the soil to pupate. In Melbourne, the adult moths emerge about four weeks later.
The adult moths have forewings that are vary from dark grey through brown to white, speckled with silver. Each wing has a row of orange spots along the termen, and a subterminal row of cream spots. The central area of each forewing has large irregular dark spot with a yellow dot in the middle. The hindwings are dark brown with similar borders to those of the forewings. The abdomen is black with orange dorsal spots and an orange anal tuft. The males often have a brown diagonal stripe across each forewing. The males have a wingspan of about 3 cms. The females have a wingspan of about 4 cms.
When the moth is threatened, it is inclined to lie down and look dead, with its wings lifted high and the abdomen curved under, displaying this orange tuft.
The caterpillars of this species are difficult to distinguish from those of Epicoma melanospila. However on rearing them through, the adult moths are easily distinguished.
The moths of this species are difficult to distinguish from those of Epicoma contristis. However the caterpillars are easily distinguished as the caterpillars of Epicoma contristis have no prominent white hairs.
The species occurs in
