Selitrichodes sp.
These were small wrinkled 5 mm wide balls at the end of stems of a casuarina tree. At least one small branch had several of these with holes ( parasitoid ?). Most were dry but a single fresh green gall on the same branch had a knobbly surface. When dissected the gall showed several thick-walled locules. These look similar to galls seen on C.glauca induced by the gall wasp Selitrichodes.
Spotted on Casuarina (? C.glauca) in a suburban park.
This is an unusual spotting for me. I hope the genus is correct. Thanks to Neil Ross for his input. Missing John La Salle !

I have not seen that particular article but seen photos of the galls on Casuarina glauca. Thanks for that - I think it has to be Selitrichodes and possibly Selitrichodes casuarinae but as I can't find anything conclusive I'll leave it at the genus level. Thanks again Neil - galls are tricky so it's really good when you have help.
An unusual spotting, indeed, and very interesting. You've definitely done your homework, so perhaps you've already seen this... http://sciencythoughts.blogspot.com/2014...
