Massachusetts Butterfly Club

The Massachusetts Butterfly Club was formed in 1992 to promote appreciating, learning about, and monitoring butterflies in the state. As a chapter of the North American Butterfly Association, the club sponsors statewide field trips, programs and annual meetings, organizes NABA Counts, and maintains a database of butterfly sightings. We are very happy to partner with BAMONA in making our butterfly records available.
