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 ...
Most species of gall wasps live as gall-formers on oaks. One of the best-known is the common oak gall wasp (Cynips quercusfolii), which induces characteristic, 2-cm in diameter, spherical galls on the undersides of oak leaves.
Andricus quercusstrobilanus, the lobed oak gall wasp, is a species [1] of gall wasp in the family Cynipidae, [2] found in North America. [3] The quercus in its specific name is the genus name for oak, while "strobilus" is derived from the Greek strobilo which means "cone", a reference to the cone shape of the gall; [4] thus the gall is sometimes called pine cone oak gall.
Andricus quercuscalifornicus (occasionally Andricus californicus), or the California gall wasp, is a small wasp species that induces oak apple galls on white oaks, primarily the valley oak (Quercus lobata) but also other species such as Quercus berberidifolia.
Atrusca brevipennata, formerly Andricus pellucidus, also known as the little oak-apple gall wasp, is a locally common species of cynipid wasp that produces galls on oak trees in North America. [1] The wasp oviposits on shrub live oak and Gambel oak leaves. [1] The larval chamber is at the center of the gall, connected to the husk by slender ...
Andricus quercuspetiolicola, also called the oak petiole gall wasp, is a species of oak gall wasp in the family Cynipidae. [1] Galls in which the larvae live and feed are formed along the midrib or petiole of white oak leaves.
Galls (upper left and right) formed on acorns on the branch of a pedunculate (or English) oak tree by the parthenogenetic generation Andricus quercuscalicis.. The large 2 cm gall growth appears as a mass of green to yellowish-green, ridged, and at first sticky plant tissue on the bud of the oak, that breaks out as the gall between the cup and the acorn.
Atrusca bella, also known as the little oak-apple gall wasp, is a locally common species of cynipid wasp that produces galls on oak trees in North America. [1] The wasp oviposits on Arizona white oak, Mexican blue oak, netleaf oak, Toumey oak, and shrub live oak. [1] The larval chamber is at the center of the gall, connected to the husk by ...
