Pumpkin Gall Wasp
Dryocosmus minusculus
Dryocosmus minusculus is an abundant species of cynipid wasp that produces galls on oak trees in California in North America. Commonly known as the pumpkin gall wasp, the wasp oviposits on the leaves of Quercus agrifolia, Quercus wislizenii, and Quercus kelloggii. In spring and summer, larvae induce round galls reaching 1 mm across. Fresh galls are pale with darker centers. Adult wasps emerge the following spring.
