Trigonaspis cupella

Phylloteras cupella, formerly Trigonaspis cupella, also known as the urn gall wasp or the banded urn gall wasp, is a species of cynipid wasp that induces leaf galls on a number of oak species in western North America.[1][2] Host species include Arizona white, blue, Engelmann, gray, leather, netleaf, scrub, and shrub oaks.[1] In the United States, galls induced by this species of wasp have been documented in California, Arizona, and New Mexico.[2] This wasp is most likely also in Mexico and Canada.[3]

The galls usually have an ombré gradient: lighter at the top, and darker toward the bottom.[1] New galls may be yellow, red, or mauve, while aging galls display a distinctly purple tint, and old galls ultimately turn brown.[1]

The wasp measures 1.3–2 millimeters in length.[4]
