General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Adult females have short/half length wings; while adult males have full length wings.
The adult females we have measured are from ~85mm long (excluding cerci) to over 100mm!.
Older nymphs have wing stubs which are similar to adult female short wings. But on comparison are obviously different.
The white stripe down the back is diagnostic for this species; easy to spot in all but the adult male.
These can be green or brown, colour is not diagnostic of species. It varies as camouflage in their local environment.
We have photographed them in Jun (nymph), Nov, Jan, Feb & Mar.
