TL0549 : Knopper gall on oak

taken 15 years ago, near to Bedford, England

Knopper gall on oak
Knopper gall on oak
A gall caused by a cynipid wasp [Andricus quercuscalicis]. Usually one or two galls can be seen at the side of the acorn, but these are completely obscuring the acorn. A relatively recent introduction to Britain, but now quite widespread. See Lairich Rig's image and detailed account NS3878 : Acorn knopper galls on oak.
