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]
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.
