General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
The 1st was the first photo on Atlas of this species, and the first sighting in SA since 1891.
Male ~14mm long & ~35mm wingspan. Female ~12mm long & ~35mm wingspan. So similar size, with females have a shorter stout body.
Males & females are both bipectinate, however, the male pectinations are noticably long than the females.
Note the colour variation from rust red, through orange to pale brown. This is not gender specific, just individual variation. All these were photographed at Ellura, so it's also independant of location.
We've photographed 10 specimens from early May to early June.
