Galls of California

Join iNaturalist members around the globe in hunting for galls during the nine-day week that runs from April 20 to April 28, then add each gall observation to the April 2024 Gall Week project.

Gall Week comes but twice a year, so mark your calendar. This year the last three days of gall week will overlap with the first three days of the City Nature Challenge (held 4/26-29), so some of our gall observations can be part of both projects.
