Andricus parmula Feron parmula, also known as the disc gall wasp, is a species of oak gall wasp in the genus Feron.

[1][2] It induces galls in a wide selection of oak species, especially white oaks,[3] and including hybrids.

[4] The galls are disc-shaped, up to 3 mm in diameter, and pale with red streaking.

[3] The galls induced by F. parmula superficially resemble the galls of Feron gigas, Andricus viscidus, and newly identified species called the "plate gall wasp" and the "orange-cap gall wasp" by Ronald Russo.

[3] Galls induced by this wasp have been documented in Oregon and California on the Pacific coast of North America.
