Philonix

Philonix is a genus of oak gall wasps in the family Cynipidae.^[1][2] Species in this genus are only known from Canada, the United States, and Mexico.^[2] The larvae of Philonix wasps induce galls on white oaks that are typically spherical, soft and fleshy.^[2] Galls are usually formed on the underside of leaves.^[2] Adult wasps are similar in appearance to species in the genus Acraspis.^[2] Many gall wasps have alternate sexual and asexual generations, but this has not been documented in Philonix.^[2]
