General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
At ~25mm long, this is the longest longhorn we've come across to date. It had serrated antennae that don't quite extend past the body.
As with many longhorns, the eyes are heavily indented and wrap around the antennae base.
This specimen got caught in a red-backs cobweb. It was lucky to survive, but we couldn't get all the cobweb off it's antennae & feet. In time it should be able to peel it off.
