Cherry red galls on leaf of the Wayfaring Tree for ID

Post by alindsay » Mon Aug 29, 2016 4:48 pm

Very attractive they are too.
Found 21st August in Hertfordshire.
I haven't seen these before, but l always look for the 'toilet' holes on the underside of the leaf to know whether I am looking at galls or fungus/rust.
I would like to know the insect causer please, if anyone can help.

A website that is good for plant galls: http://www.bladmineerders.nl/
It also includes Rust fungi which is what I use it most for and is also in English!
Have you seen my post here Puccinia cladii on the Kew LAFF list?

Hi Alison
it's so easy to miss these things if you forget to page down; these are caused by the gall midge Sackenomyia reaumurii
best wishes
