Walking down a pathway at a reserve last night I noticed that large patches of nettles had rusty coloured spots on them, is this Rust fungi ?

Also very noticeable were nettles smothered in the aphids Whitefly and Greenfly.

Think is a Gall mite that is causing this, might find something similiar on the following site.

Yep.. a rust is a fungal thing that grows on the surface of plant..... and will wipe off... This is something... probably a gall mite, that's getting inside the leaf and deforming it

Thank you very much Dunedin and Quercus! :t:

So it is a Gall mite! I had something similiar on a Willow tree a couple of years ago that is in my garden, the leaves eventually dropped very early.

That is a useful link, Dunedin, thank you.:t:
