General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills, the Riverland and elsewhere
We are staggered with the variations in the colours of some moths. We indicate they are different morphs in our site here to help people id them, but it's possible they fade. Fading is different to wearing. Some moth scales wear off and you can see their "skin" were all the scales have worn. This can make id difficult where the scale with patterns don't exist. Others can loose large chunks of their trailing wings, which can hold diagnostic patterns. And then, like here, they can have massive variations in the darkness of the scales, but the lines are just visible to id the moth; barely.
Having changed all our common names of moths whose larvae feed on agricultural plants to their native plant food, we are unable to do this with this species. It caterpillars feed on Brassicaceae, with no natives in this plant family in the region. As such, we can assume we only see them due to the copious infestations of Ward's Weed, etc, throughout the Murraylands.
