Cynips quercusechinus, the urchin gall wasp, is a species of gall wasp in the family Cynipidae. It induces its galls, which resemble sea urchins, on the leaves of oak trees. These galls are about 10mm in diameter.[1] The galls fall with the leaves in autumn, and the larvae inside of them emerge as adults in the spring.[2]

This species was first described by Carl Robert Osten-Sacken in 1870 based on specimens from California.[3]
