General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
While it's normally white, the specimen we found on Ellura was a yellow form. This makes sense as were millions of small yellow forbs flowering at the time it was found. Notice the one we found in the Adelaide Hills was white, under a white flower. Unusually the white one had no stripes at all (on the legs or carapace). Often the leg stripes are black.
The yellow one was a very small female, ~4.5mm long (body & head), while the white one was a larger female ~7mm.
