Hi Tracey. You would assign this spotting to the organism that caused it ... arlanda identified the "maker," which is a kind of wasp. So, this would go in the Arthropods category. By the way, I love galls ... big fan!

Are these galls on oak leaves caused by the same wasp that affects cherry trees?
I'm also unsure as to how this spotting should be categorised: is it animal or 'vegetable'? I would like to identify this spotting correctly; should this photo be assigned to the gall wasp entry?

As far as I know this wasp prefer the oak leaves

Does this also happen on trees not just on leaves

Nice spotting, I think it is a cherry gall, that forms on oaks due to the wasp Cynips quercusfolii.
