Acraspis quercushirta, the jewel oak gall wasp, is a species of gall wasp in the family Cynipidae, [1][2] tribe Cynipini (oak gall wasps),[3] found in North America.[4][5]

Hosts are white oaks, including bur oak, Gambel oak, Chapman oak, swamp chestnut oak, and chestnut oak.[6]

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.[6] 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.[6][7] These inconspicuous galls and their larval inhabitants overwinter and continue their development in spring before adults emerge in late May and early June.[6] These sexual generation adults mate and the females oviposit on veins on the underside of host leaves.[1][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.
