Butterfly counts are held in July. NABA sponsors almost 500 butterfly counts across the United States, Canada and northern Mexico each year. Volunteers count all butterfly species and individuals during a one-day period within a 15 mile diameter circle. The results are then published by NABA. These counts are critical in monitoring butterfly population trends, seasonality and ranges.
NABA-TC is always looking for volunteers to help with butterfly counts which are free and open to the public. Check our events calendar for information about upcoming counts.
