Adult males have wingspan of about 30 mm and translucent grey wings which easily lose their scales. The female is wingless.Food
The larvae feed on ''Eucalyptus'', ''Betula pendula'', ''Callitris'' and ''Pinus'' species. It constructs a silken case of 40–50 mm it which it lives and pupates. They attach twigs parallel to the axis of the case. Often, all the twigs are of uniform length, except for one twig which is cut longer than the others. The larvae normally only protrude the head and thorax out of the case, as these are covered in a hard skin that is coloured in a light and dark brown pattern. The soft abdomen is kept inside the protective case.References:
