Description

Leaf galls caused by mites. Looks like Aceria brachytarsus in my guide, but this time I remembered to look at the undersides of the leaves and there weren't corresponding depressions/markings to the top galls. Maybe these are just so young/small that they haven't formed yet?

On Black Walnut.
