“What the caterpillar calls the end of the world, the master calls the butterfly.”

- Richard Bach

About the Count:
The Loudoun County Annual Butterfly Count was started in 1997 under the stewardship of Bob Lyon, our local butterfly and moth expert. Data from our count is provided to the North American Butterfly Association (NABA) which stewards this nation-wide butterfly count each summer.

Butterflies are good indicators of habitat and the health of our environment because they need such a diversity of plants to develop and survive. Areas that are weedy and wild one year will show an abundance of species while a newly planted lawn (a monoculture) or an area sprayed with pesticides will be a wasteland.

Through conducting our counts we not only get to explore the fantastic world of butterflies up close, but also learn about this amazing web of life in nature.

To focus in on just the butterfly species of Loudoun, pick up a copy of our Field Guide to the Butterflies of Loudoun County.

How it Works:
Beginner butterfliers are paired with experts (all ages and experience levels are welcome). Teams meet at a specified location at 9am and begin counting. Around noon, the teams take a break for lunch. This also allows people who need to leave to do so. In the weeks following the count, we post our data here and send it to the NABA to be analyzed at regional and national levels.
This is a fun and educational activity as we learn about, identify and count as many butterflies as we can find and collect data to support protection and restoration of our environment. Use the form below to sign up.
