Callirhytis quercusfutilis, the oak wart gall wasp, is a species of gall wasp in the family Cynipidae. ^[1]

Ecology

[edit]

Range is central and eastern North America. ^[1]

The agamic generation lives in the scurfy bark of a host white oak tree root or trunk base. ^[2]^: 344 Host species include white oak, swamp white oak, overcup oak, bur oak, swamp chestnut oak, chestnut oak, dwarf chinkapin oak, and post oak. ^[3]

The sexual generation induces galls on host white oak leaves, between leaf veins and projecting slightly above both surfaces of the leaf. ^[2]^: 343 Internally, thin radiating fibers connect the larval chamber to the wall of the gall, providing the larva with nutrients supplied by the host. ^[4]
