EXTRA - Photo Specific Information:
Visually there is no way to know if this instar is ES1, 2 or 3 as there are no wings to compare. It is the only instar we have of this genus. It would need to be raised to determine more closely what it is.
General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Interesting bugs Assassins (Reduviidae), one of the few predatory/carnivorous true bugs (order Hemiptera). Most are vegetarian.
One easy diagnostic difference over the similiar Alydidae family are the large front legs as can be seen here; used to hold it's prey. Not all assassins have them, but no Alydidae's do.
A more guaranteed diagnostic, but harder to see, is that Assassin's have a curved rostrum / proboscis
