Burnettweldia corallina, formerly Disholcaspis corallina, the coral gall wasp, is a species of hymenopteran that induces galls on blue oaks in California in North America.[1] [2] The wasp oviposits at the base of leaf petioles. The detachable galls start out a mottled red-orange-yellow and over time darken to a deep brown and become brittle. This gall superficially resembles the oak galls induced by Besbicus heldae and Cynips quercusechinus.
