Andricus is a genus of oak gall wasps in the family Cynipidae.
Cynipini is a tribe of gall wasps. These insects induce galls in plants of the beech and oak family, Fagaceae. They are known commonly as the oak gall wasps. It is the largest cynipid tribe, with about 936 to 1000 recognized species, most of which are associated with oaks. The tribe is mainly native to the Holarctic.
Acraspis is a genus of gall wasps in the family Cynipidae. The following species are recognised in the genus Acraspis:
Trichagalma formosana is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris. It is endemic to Taiwan.
Aphelonyx is a genus of oak gall wasps in the family Cynipidae, comprising three known species:
Bassettia is a genus of gall wasps found in North America.
Feron kingi, the red cone gall wasp, is a species of gall wasp in the family Cynipidae.
Disholcaspis is a genus of gall wasps in the family Cynipidae. There are more than 40 species described in the genus Disholcaspis. Some Disholcaspis species induce galls that produce honeydew, a sweet liquid that attracts yellow jackets, ants, and bees. These insects then protect the galls from parasitic wasps.
Callirhytis is a genus of gall wasps in the family Cynipidae. There are more than 90 described species in Callirhytis. Wasps in this genus primarily induce wasps on oak trees in North America.
Philonix is a genus of oak gall wasps in the family Cynipidae. Species in this genus are only known from Canada, the United States, and Mexico. The larvae of Philonix wasps induce galls on white oaks that are typically spherical, soft and fleshy. Galls are usually formed on the underside of leaves. Adult wasps are similar in appearance to species in the genus Acraspis. Many gall wasps have alternate sexual and asexual generations, but this has not been documented in Philonix.
Amphibolips quercusostensackenii is a species of gall wasp in the family Cynipidae. It is found throughout eastern North America.
Druon is a genus of gall wasps in the family Cynipidae. The type species is Druon protagion. Recognised species include:
Druon ignotum is a species of gall wasp in the family Cynipidae.
Burnettweldia is a genus of oak gall wasps in the Nearctic.
Feron gigas, also known as the saucer gall wasp, is a species of gall-forming wasp in the genus Feron. It induces galls on the leaves of scrub oaks, blue oaks, and Engelmann oaks. The galls produced by its all-female generation, which emerges in winter, are 3-4 mm wide, circular with raised edges. They are red, pink, brown, or purple. The larval chamber exists as a raised bump in the gall's center. The bisexual generation produces galls that are brown and cone-shaped.
Burnettweldia plumbella, also known as the beaked twig gall wasp, is a species of gall wasp. Previously in the genus Disholcaspis, it was moved into a new genus, Burnettweldia, in 2021. This wasp induces galls on oak trees, including blue oak, leather oak, Muller's oak, and scrub oaks. The galls are up to 15 mm in diameter and brightly colored, coming in either red with yellow spots or green with yellow spots. Their name comes from the galls' pointed tip. Galls are formed in spring and summer, and adults emerge from them in November and December. The adult wasps are 3–4 mm in length.
Feron pattersonae, also known as the plate gall wasp, is a species of oak gall wasp in the genus Feron. Their hosts are among the white oaks grouping of oaks, with blue oak being common.
Kokkocynips is an American genus of gall wasps in the family Cynipidae. There are about 8 described species in the genus Kokkocynips with several others still undescribed.
Acraspis guadaloupensis is a relatively uncommon species of cynipid wasp that produces galls on intermediate oaks. The intermediate oak disc wasp was first described in 1911 and has been moved between genera more than once. Distribution is limited to California in North America. The flattened galls appear on leaves of Quercus chrysolepis, the canyon live oak.
