General Species Information:
Found on Ellura (in the Murray Mallee)
These seem to be quite variable in colour, so perhaps a species complex. But the diagnostic feature of black bands trailing the hindwing places these specimens in C. senilis.
The black blotches on it's forewings are more obvious to the naked eye.
The sharply pointed, forward facing, "mane" can be receded by the moth at will. Possibly a defense mechanism to make it appear more aggressive or larger?
Gender can be differentiated by their antenna, with the females being thread-like.
Don Herbison-Evans has enlightened us that the wonderful mane these animals have is called a "Thoracic Crest", thanks Don
