Marble wasp gall (caused by the Cynipini wasp species Andricus kollari) formed in place of a bud on an oak tree twig. On an English Oak (Quercus robur) in Swain Road, Tenterden, Kent. A female wasp lays her egg in the tissue of the host plant, inducing the plant to form the gall in which the egg hatches to a larva. The larva feeds on the tissue of the gall while developing into a wasp. By autumn the gall hardens and changes from green to brown, and when ready to fly the wasp drills a small round hole in the gall through which it emerges. Philbhu image ref:P70800388ag.
