Callirhytis perfoveata, formerly Andricus perfoveata, the leaf ball gall wasp, is a species of hymenopteran that produces leaf galls on oak trees in California in North America.

[1] The wasp oviposits on coast live oak, interior live oak, and occasionally on California black oak, and induces what appears to be a roughly spherical gall embedded within the leaf.

[2] The gall is initially bright green and turns brown as it ages.
