Paracraspis is a genus of oak gall wasps in the Nearctic. It was established by Lewis Hart Weld in 1952, [2] then re-established in 2021. [3]
The following species are grouped into Paracraspis: [3]
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:
Synergini is a tribe of gall wasps in the subfamily Cynipinae.
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.
Acraspis quercushirta, the jewel oak gall wasp, is a species of gall wasp in the family Cynipidae, tribe Cynipini, found in North America.
Druon is a genus of gall wasps in the family Cynipidae. The type species is Druon protagion. Recognised species include:
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.
Feron crystallinum, also known as the crystalline gall wasp, is a species of gall-forming wasp in the genus Feron. The galls of its all-female parthenogenic generation are pink and covered in hairs that are white, red, or brown. These galls are often massed together in clumps that can cover the underside of leaves. Individual galls are 12–14 mm high, 7 mm across, and have a single chamber for larvae. This generation emerges in late winter. In the spring, the bisexual generation of males and females induces much smaller galls with shorter hairs. F. crystallinum galls are found in all species of oaks in California.
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.
Feron atrimentum, also known as the striped volcano gall wasp, is a species of gall-forming wasp in the genus Feron. It induces galls on blue oak leaves. Like other oak gall wasps, it has two generations: a bisexual generation, and a parthenogenic female generation. The bisexual generation produces round, 3–4 millimetres (0.12–0.16 in) galls in spring that start as green or pink, and then turn brown. The unisexual generation produces conical, 4–4 millimetres (0.16–0.16 in) galls in summer that are pale with red stripes.
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.
Disholandricus is a genus of oak gall wasps found in the Nearctic biographic realm.
Feron is a genus of oak gall wasps in the Nearctic. It was established by Alfred Kinsey in 1937, then re-established in 2023.
