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.

By photographing the host and posting on iNaturalist both projects advance the ecological understanding of both host and parasite. Linking the observations with the observation fields Reference URL and Associated observation provide links to the supporting observation. The observation field Host field identifies the critical habitat in your observation.
