Australian Lepidoptera, Volume 1 (1864), Plate 9.

The caterpillars each initially live in a conical case covered in bits of chewed vegetation. When the case is secured : the caterpillar splays out the open end of the case. As the caterpillar encounters vegetation in different shades and colours, in using that vegetation,: the case becomes banded in the various shades and colours.

As the caterpillar matures, the case becomes long and thin and slightly curved. Eventually, the caterpillar grows too big to fit into the narrow end, and pupates only in the wider end, so the narrow end collapses.

The caterpillars have a black head, dark chitinous armour on the thorax, and an off-white abdomen.

The head normally is the only part of the body that is protruded from the case, although by holding the case and pulling it back gently, more of the caterpillar can be exposed. The case grows to a length of about 3 cms.
