Pergidae
A lot of individual sawfly larvae were feeding on 'sword grass' below a medium sized eucalyptus. Being near midday they would probably climb back up the tree at sunset and cluster into a mass.
Eucalyptus forest near ocean foreshore.
This is a type I have not seen before. Very different from the green eucalypus or melaleuca species. Is there a sawfly which feeds on poaceae ??? It was on a stiff grass just like this one 80km away http://www.projectnoah.org/spottings/154...

..on second thoughts no... I can't match the pale stripe down the side.
Thanks for that info Martin. I originally went with that species but thought I should back up one notch. Do you think dorsalis is good for this?
Check the third image on this link and the comment. It seems that pied color forms (like yours) occur for P. dorsalis http://lepidoptera.butterflyhouse.com.au...
I have not found a guide to the 200 australian species and my readhead one is a mystery. http://www.projectnoah.org/spottings/128...
Thank you mark for your information..
Hi OnengDyah . The individuals are about 70mm long. They look best/worst when they cluster at night. Here's a cluster of a related species... http://www.projectnoah.org/spottings/123...
