Citizen Science in Action

Butterfly counts are a hallmark of the citizen science and action North American Butterfly Association members take to protect butterfly populations.

The North American Butterfly Association has run the Butterfly Count Program in the United States, Canada, and Mexico since 1993. Each of the approximately 450 counts consists of a compilation of all butterflies observed at sites within a 15-mile diameter count circle in a one-day period. The annually published reports provide a tremendous amount of information about the geographical distribution and relative population sizes of the species counted. Comparisons of the results across years can be used to monitor changes in butterfly populations and study the effects of weather and habitat change on North American butterflies.
