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!
