Clustered Gall Wasp

Andricus brunneus


Small, red ball growing from mid rib on underside of leaf.


White Oak leaf


"the wasp that created the gall should be Andricus brunneus, which only occurs on white oaks. It looks as if this gall might have been parasitized -- it's got some damage on it and doesn't look as robust as they can look." - Joyce Gross
