The galls produced by its all-female generation, which emerges in winter, are 3-4 mm wide, circular with raised edges. They are red, pink, brown, or purple. The larval chamber exists as a raised bump in the gall's center. The bisexual generation produces galls that are brown and cone-shaped.{{Cite book |last=Russo |first=Ronald A. |url=https://www.worldcat.org/oclc/1239984577 |title=Plant galls of the Western United States |date=2021 |publisher=Princeton University Press |isbn=978-0-691-21340-8 |location=Princeton, New Jersey |pages=284–286 |language=en |oclc=1239984577}}
