General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~15mm Long with Wingspan ~42mm.
This is figured in Moths of Victoria (MoV) part 7 as Gastrinodes sp (1).
Wingspan can be a subjective measurement. We measure the wing length + body width to arrive at our wingspans. eg here 19mm wing length x 2 + body with of 4mm. However, the natural wingspan here is 31mm, ie it's naturally sitting with it's wings open. That's a HUGE difference. Yet the wing span of dead specimens is measure with their wings fully outstretched; as they are "set" to show the hindwings. Plus the majority of moths don't sit with their wings open, naturally. Usually they are closed, with wings "wrapped" around the body. As such, to compare one species of moth to another, the "naturally" sitting wingspan is of little use. The individual wing lengths + body width meathod, should also compare favourably with those measurements of dead specimens with wings fully outstretched (which is where most official wing span measurements derive).
