The Spangle Gall is caused by a tiny gall wasp, Neuropterus quercusbaccarum, and can be found on the underside of oak leaves in early autumn. It is common and widespread, and a single leaf can host up to 100 galls, each containing a single larva. The galls fall to the ground and can be seen around oak trees during autumn; the larvae continue to develop through the winter, and emerging as adults in April.

The Spangle Gall is a brown, disc-shaped gall found on the undersides of oak leaves. There are several similar, disc-shaped galls, however, that also grow on oak trees.(LINK)
