General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
The adult male was about ~55mm long, the adult female was considerably larger and just over 80mm.
The body parts of stick insects are a little harder to work out than most insects. It looks like they have 5 main parts rather than 3.
This is because the thorax is broken up into 3 distinct parts, where it often looks like one. The head is obvious, then the thorax starts with the pronotum (looks like a collar behind the head). The 2nd part of the thorax is the Mesonotum & the 3rd part is the Metanotum, followed up by the abdomen from the hindlegs back.
We have found 3 specimens, a male & 2 females, in Dec & Jan.
