Dryocosmus are a genus of gall wasps. They are cyclically parthenogenetic insects that induce galls on plants in the family Fagaceae.
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 dentimitratus is a gall forming wasp in the genus Andricus. The adults lay their eggs on various species of oak and the developing larvae causes the trees to create a large ornate gall. The oaks parasitised include Quercus frainetto, Q. petraea, Q. pyrenaica, Q. pubescens and Q. robur. The gall is formed out of the cup of the acorn. In cross-section it resembles a mushroom. It is woody, maroon, shiny and sticky. It grows up to 25 mm high and 20 mm wide. What resembles the head of the mushroom is lobed or toothed in various ways. The insect emerges from the narrowing, between the head and base.
Cynipinae is a subfamily of gall wasps (Cynipidae). Many of the approximately 1,500 described species cause galls on oaks, but some induce galls on other plant species or are inquilines of the gall-inducing species. Species occur on all continents except Antarctica, with most found in the temperate regions of the northern hemisphere. All extant cynipid species are within Cynipinae since the only other recognized subfamily is Hodiernocynipinae which is based on the fossil genus Hodiernocynips.
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. Cynipini wasps can act as ecosystem engineers. Their galls can become hosts of inquilines, and the wasps themselves are hosts to parasitoids.
Pseudoneuroterus nichollsi is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris.
Pseudoneuroterus mazandarani is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris. The species is named for the Mazandaran province of Iran where it was collected.
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 kordestanica is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris.
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.
Striatoandricus is a genus of Neotropical gall wasps (Cynipidae). There are six described species, four of which were formerly included in Andricus. All species induce galls on oaks in which their larvae live and feed.
Andricus dimorphus, also called the clustered midrib gall wasp, is a species of oak gall wasp in the family Cynipidae. Galls in which the larvae live and feed are formed in clusters along the midrib on the underside of oak leaves.
Synergus japonicus is a species of gall wasp in the family Cynipidae. Whereas most gall wasps create the galls in which they live, Synergus japonicus is an inquiline species, living in the gall created by another species of wasp. It is native to Japan, China and Russia.
Phylloteras volutellae, the conical oak gall wasp, is a species of gall wasp , tribe Cynipini , found in North America.
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 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.
