General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
A rarely recorded largish moth.
The males are smaller than the females and have bipectinate antennae; compared with females having filiform. The male we measured was ~13mm long, ~38mm wingspan. The female was ~15mm long & ~44mm wingspan
The black & white thoracic crest differentiates these from other Mnesampela species.
They have a beige hindwing bleeding to plum coloured towards the trailing half. Their forwings are a dapled mustard colour that mimics a drying gum leaf perfectly. There are even raised scales scattered across the wing that mimic the blisters in the surface of drying gum leaves.
There is a faint/indistinct wavy rust coloured line across the middle of the forewing.
4 specimens came to a night light & sheet over 4 days in April. 2 males & 2 females.
