Click here for registration information.

The Butterfly Count is an ongoing program of the North American Butterfly Association (NABA) to census the butterflies of North America (United States, Canada and partially Mexico) and to publish the results. Volunteer participants are assigned a count area with a 15-mile diameter. The volunteers conduct a one-day census of all butterflies sighted within that circle.

Volunteers are encouraged to attend the butterfly identification webinar on Sept 5 (FREE for ASNV Members; $10 for non-members).

Volunteers of all experience levels are welcome! Every team will be led by an expert. Participants are encouraged to stay with their team for the duration of the event. A tally rally will take place at 4:00 PM at Belle Haven Pizzeria at 1401 Belle Haven Road, Alexandria, Virginia 22307.

This count is organized by Larry Meade. Deadline to register is Thursday, September 7 at 9:00 PM so you can be assigned to a team on Friday. Teams will each meet at their designated count locations.

Larry Meade is president of the Northern Virginia Bird Club and a member of the ASNV Adult Education Committee. He is a frequent bird walk leader and has been involved in numerous Audubon Christmas Bird Counts and NABA Butterfly Counts. He is the compiler of the Alexandria Circle NABA Butterfly Count.

The 2022 Butterfly Count Results from the Loudoun Wildlife Conservancy

Loudoun Wildlife Conservancy has coordinated the Annual Loudoun Butterfly count since 1997. The count takes place in early August, which is the peak time for butterflies in our area. They report their data to the North American Butterfly Association (NABA), which tracks butterfly populations.

This year on August 6, a typical warm, humid summer day, 60 volunteers set out to count as many butterflies as they could find in a single day. It was their 26th Annual Butterfly Count, and they tallied 3,756 butterflies of 45 species in an area of about 178 square miles in the northwestern corner of Loudoun County.

When the count day is over, team leaders tabulate their results, which are consolidated into a report submitted to the NABA. NABA collects reports from all over the country and makes them available to researchers.

Anne Ellis, Butterfly Count Coordinator, has written a very informative article, “How Does One Count Butterflies?“, in which she describes this year’s count experience and answers the question, “Exactly how does one count butterflies?”

If you would like to know which species have been seen during previous years, you can view butterfly count data and reports.  A summary report of species count by year can be viewed here.

The 2023 count will be on Saturday, August 5. Please join the Loudoun Wildlife Conservancy and count the butterflies!
