General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
A common moth which has some unique characteristics.
The larva curl up at the base of plants looking like new, unfurled leaves.
The adults have a forked horn projection out the front of it's head. It's hairless and not part of the palps; a separate structure.
Males & females have bipectinate (2 rowed) antennae. The male pectinations are very long, while the female's are very short.
We have photographed 17 specimens. 4 Larvae in July & Aug, 5 males in Apr & May and 7 females in Apr (one indeterminate gender in May). This indicates they "hibernate" as eggs over winter, spring & summer, hatching in early autumn and finishing their life cycle before winter sets in.
