General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
There are few trusted images of Cryptocheilus sp.
Assuming the bands on the abdomen are one of the diagnostic traits of this genera, C bicolor has quite a thick black abdomen band; and is fairly hairy.
S1 & S2 were about 30mm long, ~50mm wingspan. S3 looked identical to the others, except for the black stripe across the top of the head. However, it was significantly smaller at only ~21mm long. Different gender, different species? Not sure.
Cryptocheilus sp wing tips seem to often have black edges, which here are missing. Possibly due to the wings being so worn. It's possible the black edging is gender related.
Photographed 3 specimens in January.
