Amphibolips confluenta, gall, Oak Apple Gall
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.
