Oak galls of the wasp Adleria weldi occur on one year-old acorns.
Young, green galls secrete honeydew, but at maturity galls turn brown and
drop from their host. Shown here on Quercus myrtifolia, this wasp
also attacks Q. laurifolia in the southeastern United States. This species is incorrectly placed in Adleria and should be moved to the genus Andricus.
