Amphibolips quercuspomiformis, also known as the apple gall wasp or live oak apple gall wasp, is a species of gall wasp. It induces galls in coast live oak and interior live oak trees. Like many gall wasps, it has two alternating generations which induce differing galls: an all-female parthenogenic generation, and a bisexual generation. The galls formed by the unisexual generation in summer are spherical, up to 40 mm in diameter, and covered with short spines. They form on stems and are green or red when new, then turn brown. The galls formed by the bisexual generation in spring are small, shaped like toadstools, and occur on leaves.[2][1]
