Cynips is a genus of gall wasps in the tribe Cynipini, the oak gall wasps. One of the best known is the common oak gall wasp, which induces characteristic spherical galls about two centimeters wide on the undersides of oak leaves.
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.
Aphelonyx is a genus of oak gall wasps in the family Cynipidae, comprising three known species:
Atrusca is a genus of gall wasps in the family Cynipidae. It consists of approximately 50 species, and is found in North and Central America.
Synergini is a tribe of gall wasps in the subfamily Cynipinae.
Amphibolips is an American genus of gall wasps in the family Cynipidae. There are about 57 described species in the genus Amphibolips with several others still undescribed.
Antron is a genus of gall wasps in the tribe Cynipini, the oak gall wasps. Some authors have included it within the genus Cynips but it was recently resurrected. The genus was established by Alfred Kinsey in 1930.
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.
Druon fullawayi, also known as the yellow wig gall wasp, is a species of gall wasp in the family Cynipidae. It was previously placed in the genus Andricus. William Beutenmüller described the female adult wasps as 1.5-2.25 mm long, black with brown mouth parts and brown legs. The galls of D. fullawayi are tan or yellow, woolly, and measure 5-8 mm in diameter. Each gall holds a single chamber for larvae. They are found in California on oak trees, especially Quercus lobata.
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.
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.
Feron bakkeri, also known as the pinched leaf gall wasp, is a relatively uncommon species of gall-inducing hymenopteran. They produce pink leaf galls on Oregon oaks and scrub oaks. The distribution of this wasp is California and Oregon in North America. It was previously placed in the genus Andricus.
Besbicus mirabilis, formerly Cynips mirabilis, also known as the speckled gall wasp, is a common species of cynipid wasp that produces galls on oak trees in North America. This wasp oviposits on the midrib of the underside of Oregon oak leaves. One to three detachable galls per leaf have been observed. The larval chamber is at the center of the gall, connected to the husk by slender, radiating fibers. The second generation of this wasp induces bud galls. The galls may be parasitized by moth larva or eaten by earwigs or other enterprising arthropods before the larva complete their development. This wasp is present on the Pacific coast of North America from British Columbia to northern California.
Feron is a genus of oak gall wasps in the Nearctic. It was established by Alfred Kinsey in 1937, then re-established in 2023.
