gall

The sexual generation forms catkin galls, c. 2 mm long, bearing white hairs that are much longer then the diameter of the gall. Often the galls are partly hidden by the bud scales; often also the catkins don’t extend to their normal length. Often high in the canopy of mature trees. Galls are mature end of May.
