A Brief Delving into the Lives of Some Gall Wasps Associated with Oaks, Chinquapins, and Tanoak

Join Dr. John DeMartini, a Humboldt State University professor emeritus with a passion for regional natural history, to learn more about the tiny, gentle wasps of the family Cynipidae that collectively produce galls on members of the oak and rose families.  Galls are tumors produced by specific insects, mites, fungi, bacteria, and viruses.  Cynipid gall wasps produce from very simple to very ornate galls serving as habitat for egg development to adult.  A goal of this talk is for the audience to become aware of galls and consequently to enjoy time in the field observing their amazing biology and architecture.
