Acraspis is a genus of gall wasps in the family Cynipidae. The following species are recognised in the genus Acraspis:
Potentilla simplex, also known as common cinquefoil or old-field five-fingers or oldfield cinquefoil, is a perennial herb in the Rosaceae (rose) family native to eastern North America from Ontario, Quebec, and Labrador south to Texas, Alabama, and panhandle Florida.
Potentilla canadensis, the dwarf cinquefoil, is a species of cinquefoil native to North America.
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.
Feron kingi, the red cone gall wasp, is a species of gall wasp in the family Cynipidae.
Diastrophus is a genus of gall wasps in the family Cynipidae. There are at least eight described species in Diastrophus.
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.
Amphibolips quercusinanis, known generally as the larger empty oak apple wasp, is a species of gall wasp in the family Cynipidae.
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.
Amphibolips confluenta, known generally as the spongy oak apple gall wasp, is a species of gall wasp in the family Cynipidae. Its range includes Ontario, Quebec, and much of the eastern United States. Hosts include Quercus buckleyi, Quercus coccinea, Quercus falcata, Quercus ilicifolia, Quercus marilandica, Quercus rubra, Quercus shumardii, and Quercus velutina.
Cynips quercusechinus, the urchin gall wasp, is a species of gall wasp in the family Cynipidae. It induces galls in the leaves and leaf buds of blue oak and scrub oak. Like other oak gall wasps, it has two generations: a bisexual generation, and a parthenogenic female generation. In spring, the hatching bisexual generation produces hollow green galls in leaf buds. In summer, the unisexual generation induces its galls, which are red or pink and resemble sea urchins, on the undersides of leaves. These galls are about 10 millimetres (0.39 in) in diameter. The galls fall with the leaves in autumn, and the larvae inside of them emerge as adults in the spring and lay their eggs.
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.
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.
Andricus quercusstrobilanus, the lobed oak gall wasp, is a species of gall wasp in the family Cynipidae, found in North America. The quercus in its specific name is the genus name for oak, while "strobilus" is derived from the Greek strobilo which means "cone", a reference to the cone shape of the gall; thus the gall is sometimes called pine cone oak gall.
Phylloteras volutellae, the conical oak gall wasp, is a species of gall wasp , tribe Cynipini , found in North America.
Druon ignotum is a species of gall wasp in the family Cynipidae.
Callirhytis quercusfutilis, the oak wart gall wasp, 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.
Diastrophus nebulosus is a species that forms galls. Its common name is the blackberry knot gall wasp. Its host plant is Rubus flagellaris.
Heteroecus sanctaeclarae, also known as the mushroom gall wasp, is a species of cynipid wasp that induces galls on huckleberry oaks and canyon live oaks on the Pacific coast of North America.
