General Species Information:
Found in the Adelaide Hills and possibly elsewhere
~17mm long. These only have 3 antennae segments, which is less than most others at 4 or 5. However, the colour banding makes them look like 4 segments, so you need to pay close attention to the actual segment separtion; not just colour.
Notice the spurs on each antenna base under the head.
It seems some specimens have longer spines than others. Possibly a gender difference?
We have photographed 9 adult specimens in Jan, Feb, Mar, Apr, May & Nov.
