I'm guessing its a myxomycete, but even after looking at a small piece under a microscope I still don't have a clue.

I wonder if it's a gall. Long ago (over more than one year) I saw masses of such crimson things on shrubs in the Mt Ginini area and my recollection is that a dissection showed what I'd found to be a gall. From recollection they were confined to one of the pea flowers (Bossiaea comes to mind but I may be mis-remembering my identificationof the host). The striking colour made it very easy to see them froim a distance.

I've moved the sighting into the Unidentified Insects section for others to look at.

While looking for something else I came across a photo like this in Roger Farrow's 'Insects of south-eastern Australia'. See page 158, where the galls are attributed to a wasp of the Chalcidoidea - and they are on a Bossiaea!

Heino, thanks for persisting with this. I now suspect it could be a gall perhaps either a mite or small wasp. Unfortunately since I found this I've been fighting the dreaded lurgy - its well ahead on points but I'm beginning to stage a come back. Anyway I've been unable to get out to have a further more in depth look, maybe in a week or two.

Hi guys
I have found a very good reference to this in the latest BowerBird newsletter (author Ken Walker):
See pages 17 & 18 of:
http://researchdata.museum.vic.gov.au/BowerBird_Bugle/Edition_49.pdf
In the accompanying photo the galls are also on a Bossiaea at higher altitudes, attributed to an unknown wasp, and also refer to Roger Farrow's book.

Thanks Michael, hopefully someone will send him a specimen and perhaps he will be able to rear out the invertebrate, but I wonder if a dying plant part will still support a developing parasite.

Yes Ken, I had the same question. I hope he can do it too.

Its a common insect induced gall on found on bossiaea foliosa but to date I have not succeeded in rearing the culprit out but still trying. As Ken says you need a mature gall to allow the inducer to complete development and emerge. Another method would be to put a sleeve around the gall to trap anything that emerges although this may also include hyper parasites.

Ken Walker has succeeded in rearing the Bossiaea gall wasp and has identified it to genus. It is a new species of Tanaostigmodes (family Tanaostigmatidae). He will work with Dr John LaSalle to describe and write a paper on the new species and give it a name. See Ken’s excellent and detailed essay on the subject in the BowerBird newsletter at:-
http://researchdata.museum.vic.gov.au/BowerBird_Bugle/Edition_50.pdf
I have made a new suggestion for the ID.
