Andricus fullawayi Druon fullawayi, also known as the yellow wig gall wasp, is a species of gall wasp in the family Cynipidae.

[2] William Beutenmüller described the female adult wasps as 1.5-2.25 mm long, black with brown mouth parts and brown legs.

The galls of D. fullawayi are tan or yellow, woolly, and measure 5-8 mm in diameter.

Each gall holds a single chamber for larvae.

They are found in California on oak trees, especially Quercus lobata.
