Two-horned Gall Wasp
Dryocosmus dubiosus
Dryocosmus dubiosus is an abundant species of cynipid wasp that produces galls on oak trees in California in North America. Commonly known as the two-horned gall wasp, the wasp oviposits on the leaves and catkins of coast live oaks and interior live oaks. After the eggs hatch, the resulting gall form looks like it has a set of bull's horns.
