General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
There are a few similar looking moths that are quite variable. There's also C. arachnitis which is close. C. severata is probably a species complex. We have decided on this one based on a range of factors including wing shape, pattern, colour, etc.
The females we measured were slightly larger @ ~19mm (S2) & ~20mm (S3) wingspan compared to the male @ ~17mm (S4) wingspan.
Males have thick antennae compared with females, but it's not very obvious.
We haven't encountered them very often photographing only 6 specimens, with 2 males, 2 females & 2 indeterminate in March & April.
