General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
The 1st two specimens were recorded on the same day at Ellura.
Notice the 3rd specimen (Adelaide Hills) has more transparent edges, and a black streak down the side.
All 3 specimens have different ventral patterns on their abdomen. We're not sure if these are different species or variations on the same species.
Also notice the white face markings, these are not reflections but white pigment
