Contarinia zauschneriae, also known as the California fuchsia gall midge, is a species of gall midge that induces roselle-form bud galls on Epilobium canum, a flowering plant of western North America.{{cite web |title=Contarinia zauschneriae (California Fuchsia Gall Midge) |url=https://www.inaturalist.org/taxa/495532-Contarinia-zauschneriae |website=iNaturalist |access-date=2023-11-09 |language=en-US}}{{Cite book |last=Russo |first=Ronald A. |url=https://www.degruyter.com/document/doi/10.1515/9780691213408/html |title=Plant Galls of the Western United States |publisher=Princeton University Press |year=2021 |isbn=978-0-691-21340-8 |oclc=1239984577 |lccn=2020949502 |pages=231 |language=en-us |doi=10.1515/9780691213408 |s2cid=238148746 }} The galls are typically 25 millimeters high and about 15 millimeters around. The coloration roughly mimics that of a stereotypical red rosebud, with red on the upper half where the petals would be and green-yellow at the base where the leaflets would be. The type species was collected by Ephraim Felt in the Puente Hills, near Whittier, California, in 1910.{{Cite journal |date=1953 |journal=Bulletin of the California Insect Survey |title=The Gall Midges of California |publisher=University of California Press |volume=2 |issue=2 |url=https://essig.berkeley.edu/documents/cis/cis02_2.pdf |access-date=2023-11-09 |page=143 |via=essig.berkeley.edu }}
