Wonky acorns

The distorted acorn in the picture above is called a Knopper Gall. It’s a result of the tiny gall wasp, Andricus quercuscalicis laying its eggs in the base of the flower of our native Pedunculate Oak. The larva secretes a substance that distorts the developing acorn. During August these galls become brown and sticky, and after wintering on the ground, the adult wasp emerges. A second generation then develops in the catkins of Turkey Oak.

This link presented by David Attenborough, shows the life cycle of the wasp.
