The Oak Apple Gall Wasp (Biorhiza pallida) is a hymenopterous insect of the family Cynipidae. The adult wasp reaches a length of between 1.9 and 2.3 mm, the larvae measuring between 3.5 and 6 mm in length. The female wasp injects her eggs into a bud on the oak branch which develops into a gall in which the larvae develop, later pupating within the gall before emerging as an adult wasp.
