General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Head & body is ~9mm long, with a wingspan of ~28mm.
Very similar wing patterns to our Spider-mimicking moth males, but the antennae are very different. Here they are "hairy"/bushy, and the females are not flightless; looking like the males. The bushy "hairs" on the male antennae are not hairs at all, but very thin scales, hence we put the word "hair" in relation to moths in quotes. They looks like hairs but are scales, different structures. Bushy is a better general term.
