The developing white Oak Apples shown here are on an oak tree. They are galls caused by wasps in the family Cynipidae. They develop when a female adult wasp lays an egg in a leaf bud. The larva that hatches from the egg feeds on the gall tissue caused by its secretions. It lives in the center of the gall, becoming eventually a pupa and finally an adult wasp, thus completing the wasp's life cycle. In eastern North America, Amphibolips confluenta is a common species of wasp that forms such Oak Apple Galls.
