Distinguished from other Callirhytis by its specific association with flower on coast and interior live oaks. The galls induced on flower buds differ in location from leaf galls or stem galls produced by related species. Accurate identification typically requires examination of gall , species, and gall location on the plant.

Habitat
Associated with oak woodlands and savannas supporting coast live oak or interior live oak. The 's is defined by the presence of its specific plants rather than particular abiotic conditions.
Distribution
Documented in California, North America. Distribution corresponds to the range of its oaks: coast live oak along the California coast and interior live oak in the Sierra Nevada foothills and interior ranges.
Diet

Host Associations
- Quercus agrifolia - coast live oak; flower
- Quercus wislizeni - interior live oak; flower
Behavior
Induces formation on flower through and subsequent chemical manipulation of tissue. The develops within the gall, consuming nutritive produced by the plant. details and whether this exhibits the complex common in cynipids have not been documented.
Ecological Role
As a inducer, creates microhabitats that may be utilized by other organisms. The galls represent a form of that diverts resources from normal flower development. Specific or associated with this have not been documented.
