Andricus quercuscalifornicus can induce and inhabit the galls of a variety of oak species, but they are primarily found in the galls of the Valley Oak. Due to this, they are usually found in areas such as riparian forests, open foothill woodlands, valley savannas, plant groves, and suburban areas. The wasps typically induce galls on the twigs ...
Dryocosmus minusculus is an abundant species of cynipid wasp that produces galls on oak trees in California in North America. [1] [2] Commonly known as the pumpkin gall wasp, the wasp oviposits on the leaves of Quercus agrifolia, Quercus wislizenii, and Quercus kelloggii. In spring and summer, larvae induce round galls reaching 1 mm across.

[1] [2] Commonly known as the two-horned gall wasp, the wasp oviposits on the leaves and catkins of coast live oaks and interior live oaks. [1] After the eggs hatch, the resulting gall form looks like it has a set of bull ...

Trichoteras coquilletti, formerly Andricus coquilletti, also known as the little oak-apple gall wasp, is a fairly common species of cynipid wasp that produces galls on oak trees in North America. [1] This wasp oviposits on the underside of the leaves of huckleberry oaks and canyon live oaks . [ 1 ]
Andricus confertus, the convoluted gall wasp, is a fairly common species of cynipid wasp that produces galls on oak trees in California in North America. This gall, with its pink, brain-like appearance, is actually a cluster of galls. [1] In summer, parthenogenetic female larvae induce these galls on the underside of valley oak leaves, along ...
Callirhytis perfoveata, formerly Andricus perfoveata, the leaf ball gall wasp, is a species of hymenopteran that produces leaf galls on oak trees in California in North America. [1] The wasp oviposits on coast live oak , interior live oak , and occasionally on California black oak , and induces what appears to be a roughly spherical gall ...
