Acraspis quercushirta, the jewel oak gall wasp, is a species of gall wasp in the family Cynipidae, [2] [3] tribe Cynipini (oak gall wasps), [4] found in North America. [5] [6]

Hosts are white oaks, including bur oak, Gambel oak, Chapman oak, swamp chestnut oak, and chestnut oak. [1]

Ecology and Life History

Like most oak gall wasps, this species has two generations per year - one asexual (or agamic) and one sexual, with each generation producing distinct galls. [1] The wingless females of the asexual generation emerge from their galls in fall and climb up an oak tree to oviposit in bud scales thereby inducing the gall development. [1] [7] These inconspicuous galls and their larval inhabitants overwinter and continue their development in spring before adults emerge in late May and early June. [1] These sexual generation adults mate and the females oviposit on veins on the underside of host leaves. [2] [8] The induced gall is detachable, oval in shape, and the color can range from white to yellowish to tan or brown. The surface is fissured into facets that end in a short, hard point, reminiscent of jewelry. [9] These galls typically fall with the leaves in autumn with the asexual female adults emerging shortly thereafter.

<span class="mw-page-title-main">Cynipini</span> Tribe of wasps

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.

Acraspis is a genus of gall wasps in the family Cynipidae. The following species are recognised in the genus Acraspis:

<i>Trichagalma formosana</i> Species of wasp

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 is a genus of oak gall wasps in the family Cynipidae, comprising three known species:

Bassettia is a genus of gall wasps found in North America.

<i>Disholcaspis</i> Genus of gall wasps

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.

<i>Callirhytis</i> Genus of wasps

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.

<i>Andricus dimorphus</i> Species of oak gall wasp

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.

<i>Philonix</i> Genus of wasps

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.

<i>Burnettweldia plumbella</i> Species of insect

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.

<i>Druon quercuslanigerum</i> Species of gall wasp

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.

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.

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.
