Andricus quercuscorticis
Andricus quercuscorticis is a gall wasp that causes galls on native oaks.
The agamic galls are ovoid; they occur in clusters and are embedded in the bark on the tree-trunk; eventually only the empty galls or sockets persisting. They are usually found in callus tissue that forms around wounds on the main trunk.
The sexual galls are in buds.
The agamic barnacle galls (Andricus sieboldii and testaceipes) also form on tree trucks, usually close to the ground, but are conical and ridged.
