Nambouria sp.
A curious growth along the leaf veins flaring above (red) and below (yellow). These are caused by a pteromalid wasp and tentatively placed in the genus Nambouria. "The developing larva can be found feeding inside the gall within an oval gallery."
Eucalyptus leaf
Only one single affected leaf with eight galls. ID thanks to the ever observant Argybee. NB The species is possibly Nambouria xanthops http://onlinelibrary.wiley.com/doi/10.10...

Interesting spotting, Martin. Saw one today with galls along the midvein - had to refer to yours for an ID !
That's a pretty convincing ID for a distinctive gall.
Thank you Argy Bee.
I think the artist might be Nambouria sp. - a gall wasp just started causing a problem in NZ... http://www.nzffa.org.nz/farm-forestry-mo...
Thank you AntónioGinjaGinja. I am completely stumped with this one. Is it viral? It was probably infected when the leaf was a bud.
Great cache Martinl,realy bizarre,very strange formation,like you say let's see if we find the artist :)
Thanks Mark, but who is the artist?
Fascinating little art-works martin.
