Eggs hatch in early spring as leaf buds begin to open. Larvae develop quickly in leaf tissue and stimulate the development of small, beige-colored galls resembling kernels of wheat. After mating, females lay eggs in post oak twigs and branches. These eggs remain dormant for 3 to 5 months. Then they hatch and stimulate the formation of galls of the asexual generation.
Mouthparts are for chewing.
This cynipid wasp species only affects post oak trees. Adults can be reared from galls pruned from trees and placed in plastic bags when larval development is completed. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
