General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Head & body ~15mm, wingspan ~43mm.
This is a species complex; meaning there are different species in the group that match the known diagnositcs. A revision of the species needs to be done to determine new diagnostics to split the group into separate species.
Both genders have bipectinate antennae, however the pectinations are tiny on the female looking like filiform antennae to the naked eye, or the wrong angle.
The Nisista MoV3, shown below, is our most common crest moth. It's difficult to find the few of these rarer species amongst the hoards of the others.
We found 2 specimens, both in May.
