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 ...
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 ...
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.

Dryocosmus dubiosus is an abundant species of cynipid wasp that produces galls on oak trees in California in North America. [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 ...
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 ...
Callirhytis serricornis, formerly Andricus serricornis, the kernel flower gall wasp, is a species of hymenopteran that produces galls on oak trees in California in North America. The wasp oviposits on coast live oak and interior live oak and induces a gall shaped roughly like a bottle or vase. The gall is brown in the first generation, and red ...
Quercus douglasii, known as blue oak, is a species of oak endemic to California, common in the Coast Ranges and the foothills of the Sierra Nevada. [4] It is California's most drought-tolerant deciduous oak, [5] and is a dominant species in the blue oak woodland ecosystem. It is occasionally known as mountain oak and iron oak. [6] [7]
