Feron kingi, the red cone gall wasp, is a species of gall wasp in the family Cynipidae.
Heteroecus pacificus, the beaked spindle gall wasp, is a species of gall wasp in the family Cynipidae. According to Ron Russo's book, Plant Galls of California and the Southwest, the galls appear on canyon live oak and huckleberry oak.
Heteroecus is a genus of gall wasps in the family Cynipidae. There are about seven described species in the genus Heteroecus.
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.
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.
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.
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.
Feron parmula, also known as the disc gall wasp, is a species of oak gall wasp in the genus Feron. It induces galls in a wide selection of oak species, especially white oaks, and including hybrids. The galls are disc-shaped, up to 3 mm in diameter, and pale with red streaking. Adult females emerge in April. The galls induced by F. parmula superficially resemble the galls of Feron gigas,Andricus viscidus, and newly identified species called the "plate gall wasp" and the "orange-cap gall wasp" by Richard Russo. Galls induced by this wasp have been documented in Oregon and California on the Pacific coast of North America.
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.
Feron pattersonae, also known as the plate gall wasp, is a species of oak gall wasp in the genus Feron. Their hosts are among the white oaks grouping of oaks, with blue oak being common.
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.
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.
Andricus pedicellatus, the hair stalk gall wasp, is a fairly common species of cynipid wasp that produces long spindly leaf galls on blue oaks on the Pacific coast of North America.
Besbicus is a genus of gall-inducing cynipid wasp found in North America. Several species now classed as Besbicus were formerly considered to be a part of the genus Cynips. Besbicus was originally described as a subgenus by Alfred Kinsey in 1929. Circa 2010, one group of entomologists noted that it was "possible that the nearctic genera Antron and Besbicus were erroneously synonymized to Cynips".
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.
Diplolepis californica, formerly Rhodites californicus, also known as the leafy bract gall wasp, is a species of cynipid wasp that induces galls on wild roses on the Pacific coast of North America. D. californica induces club-shaped bud galls that naturalist Richard A. Russo describes as "distinguished from all others by the flat, leafy lobes that emanate from the main gall body and look like aborted leaflets". Each gall contains multiple larval chambers. One of host plants of the leafy bract gall wasp is Rosa californica.
Phylloteras cupella, formerly Trigonaspis cupella, also known as the urn gall wasp or the banded urn gall wasp, is a species of cynipid wasp that induces leaf galls on a number of oak species in western North America. Host species include Arizona white, blue, Engelmann, gray, leather, netleaf, scrub, and shrub oaks. In the United States, galls induced by this species of wasp have been documented in California, Arizona, and New Mexico. This wasp is most likely also in Mexico and Canada.
