Question
I found this group of leaves in Easton CT. Along a sunny open trail. It looks like a grape leaf but what are these strange red spikes all over it?
Answer
Dear gingerbread, you've photographed galls on the leaf. The species is called grape tube gallmaker (Schizomyia viticola), a species of midge. Best wishes.
