Dryocosmus dubiosus

Dryocosmus dubiosus is an abundant species of cynipid wasp that produces galls on oak trees in California in North America.[1][2] Commonly known as the two-horned gall wasp, the wasp oviposits on the leaves and catkins of coast live oaks and interior live oaks.[1] After the eggs hatch, the resulting gall form looks like it has a set of bull's horns.[1]
