Besbicus conspicuus, formerly Cynips conspicuus, also known as the fuzzy gall wasp, is a common species of cynipid wasp that induces globular stem galls on white oak trees on the west coast of North America.

[1] This gall is solid but for the central larval chamber.

[1] After the wasp emerges, beetles sometimes chew through the husk to consume the tissue inside.

[1] This wasp is found west of the Sierra Nevada range in California in North America.
