General Species Information:
Found on Ellura (in the Murray Mallee)
About 12mm head & body length, with approx 32mm wingspan.
The hindwings mimic the forewings along the inner margin (body edge), with dark scalloping along the outer margin (trailing edge), but then fade to plain brown in the middle.
Most interesting with this species is the raised scale tufts behind the head. Almost impossible to see in dorsal view without a flash reflecting off them. The flash shows them to be metallic and a dark gold colour. In some views it appears to be a single horn, but elsewhere you can see it's two distinct tufts leaning toward each other. As the smaller scales wear down, the tufts become more visible.
Thanks to Don Herbison-Evans for pointing out these were all male specimens.
