Neuroterus is a genus of gall wasps that induce galls on oaks in which the wasp larvae live and feed. Some species produce galls that fall off the host plant and 'jump' along the ground due to the movement of the larvae within.
Galeopsomyia is a New World genus of hymenopteran insects of the family Eulophidae. The genus is a hyperparasitoid of other gall-inducing wasps of the genera Eurytoma and Torymus.
Cynips quercusfolii, also known as the cherry gall wasp, is a gall wasp species in the genus Cynips and family Cynipidae. The species is important for the production of commercial nutgall formed on Quercus lusitanica . Galls are located on the underside of leaves, with the majority of galls being on the second and third veins from the petiole of the leaf.
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.
Andricus quercuscalifornicus, or the California gall wasp, is a small wasp species that induces oak apple galls on white oaks, primarily the valley oak but also other species such as Quercus berberidifolia. The California gall wasp is considered an ecosystem engineer, capable of manipulating the growth of galls for their own development. It is found from Washington, Oregon, and California to northern regions of Mexico. Often multiple wasps in different life stages occupy the same gall. The induced galls help establish complex insect communities, promoting the diversification in niche differentiation. Furthermore, the adaptive value of these galls could be attributed their ecological benefits such as nutrition, provision of microenvironment, and enemy avoidance.
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.
Bassettia pallida is a species of gall wasp found in the Southern United States. This species was described by American entomologist William Harris Ashmead in 1896. B. pallida reproduces asexually in galls it induces on oak trees. The parasite Euderus set, a eulophid wasp, has B. pallida as a host and manipulates its behavior.
Belonocnema is a genus of oak gall wasps in the family Cynipidae, found in the United States from Texas, east to Florida. All species induce galls on section Virentes oaks and have both sexual and asexual generations. The asexual generation galls form as small balls on the underside of leaves, and the sexual galls form on roots. A number of inquiline, parasitoid, and hyperparasitoid wasp species have been reared from Belonocnema galls.
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.
Andricus quercuspetiolicola, also called the oak petiole gall wasp, is a species of oak gall wasp in the family Cynipidae. Galls in which the larvae live and feed are formed along the midrib or petiole of white oak leaves.
Disholcaspis quercusmamma, the oak rough bulletgall wasp, is a species of gall wasp in the family Cynipidae. The quercus in its name is the genus name for oak, while "mamma" is Latin for "breast", presumably a reference to the "nipple" on the gall.
Acraspis quercushirta, the jewel oak gall wasp, is a species of gall wasp in the family Cynipidae, tribe Cynipini, found in North America.
Druon quercuslanigerum is a species of gall wasp that forms galls on Quercus virginiana, Quercus geminata, Quercus fusiformis, and Quercus oleoides. There are both asexual and sexual generations. The asexual generation forms galls on the leaves whereas the sexual generation forms galls on the catkins. It can be found in the southern United States and Mexico. Predators of this species include the green parakeet.
Andricus hispanicus is a parthenogenetic species of wasp which causes the formation of marble galls on oak trees. The galls caused by the agamous generation are similar to the closely related Andricus kollari.
Neuroterus valhalla is a species of gall wasp from North America that forms galls on the Southern Live Oak. It was first discovered on the campus of Rice University.
Belonocnema kinseyi is a species of gall wasp that forms galls on Quercus virginiana and Quercus fusiformis. There are both asexual and sexual generations. The asexual generation forms galls on the underside of leaves whereas the sexual generation form galls on the roots. It can be found in the United States, where it is known from Louisiana, Mississippi, Oklahoma and Texas. It, along with the other described Belonocnema species, have been used to study speciation.
Belonocnema fossoria is a species of gall wasp that forms galls on Quercus geminata. There are both asexual and sexual generations. The asexual generation forms galls on the underside of leaves whereas the sexual generation form galls on the roots. It can be found in the United States, where it is known from Georgia and Florida. It, along with the other described Belonocnema species, have been used to study speciation.
