General Species Information:
Found on Ellura (in the Murray Mallee)
Normally we use common names that we find on the net, but clearly being in a semi-arid environment, calling something "Alpine" really doesn't fit
We found & captured 15 specimens of this species in one night; equally males & females. They were quite variable and photo artefacts played havoc with id. eg notice the white spots hide easily depending on the camera/lighting angle. The bronze colour also washed out easily in flash light.
The females we found appeared to have stronger markings than males; this is not always the case.
These beautiful moths range from plain, pale brown to a magic bronze colour. We have grouped the photo's by male & female, to show differences between specimens. Hopefully differences between gender also stand out clearly.
Males are about 10mm long, with wingspan of 25mm. Female bodies are a bit shorter at about 8mm long, but with the same wingspan as the male. The under-wings don't appear much different between the genders, but the ventral shots show the significant difference in the body shapes; with males being long & thin while females are short & fat.
Also notice the antennae differences; males have feathery antennae while females are thread like; a common situation for moths. This implies the females emit pheromones that attract males. While often males are attracted to night light, it's possible here the females were and the males followed the scent; or they could both be attracted to the light.
