Unknown Moth

Dear Heinz57,
This is a Moth, though we haven’t been able to come up with a conclusive identification.  We also don’t know if her wings failed to expand after metamorphosis, or if this is a flightless species with vestigial wings.  Many female Tussock Moths are flightless, and the markings on your specimen match those of
Oligeria hemicalla pictured on the ButterflyHouse website, but we are unable to locate an image of a female moth.  The Painted Apple Moth is an example of a Tussock Moth in the family Lymantriidae that has a wingless female.  The photos on Wikipedia indicate that it is not your species, though the eggs look quite similar.  Perhaps one of our readers will be able to supply an identification.

Unknown flightless moth lays eggs in Australia
Hi Daniel and Heinz57:
The looks like a female Australian Bagmoth, Cebysa leucotelus (Psychidae). It is native to southern Australia and has recently shown up in New Zealand. Apparently the larvae feed on lichens growing on tree trunks, rocks, etc. and the lichen fragments get incorporated into the larval cases, or ‘bags’. Only the females are flightless. Regards. Karl
