Close-up of a distorted knopper gall growth on an acorn (from a Pedunculate oak tree - Quercus robur) caused by the parasitic larva of a cynipid gall wasp (Andricus quercuscalicis). The gall wasp larva develops within a hard inner gall, providing it with both food and protection. Photographed in Dorset, UK, in September. | |
