Annual Butterfly Count, Manassas Circle
Saturday, July 20, beginning at 10 am. RSVP required to firstname.lastname@example.org, 703-490-5200.
Help count butterflies for the annual 4th of July Butterfly Count and learn more about butterfly populations close to home. This count is part of a national program led by the North American Butterfly Association (NABA), which compiles information about butterfly populations and distribution that is used to study effects of climate and habitat change on North American butterflies.
Here in Prince William on July 20, we'll form teams and see how many butterflies we can find within our count circle. We submit our compile results to NABA's national database for butterflies. We are also seeking tips on specific areas to survey - pleas
August 6, 2017 -- Led by Prince William Conservation Alliance, 29 butterfly enthusiasts formed teams and surveyed a 113,000 acre territory centered at Manassas Airport on August 6. Our goal was to identify and count butterflies.
It was a rewarding experience for all. Volunteer Dave Govani says, "It’s always a pleasure to participate with like-minded individuals in a meaningful citizen science activity that is both fun and a learning experience."
All told we saw 49 different species and 703 individuals. Highlights included some caterpillars - two Black Swallowtails and five Silvery Checkerspots.
With 111 sightings, Zabulon Skippers were the butterfly of the day. Cabbage Whites came in second, with 60 individuals, followed by Pearl Crescents and Silver-spotted Skippers.
We spotted a lone Juniper Hairstreak at Merrimac Farm WMA and were excited to find an American Snout at Manassas National Battlefield Park. We found Sachem Skippers and Eastern Tiger Swallowtails in every survey sector.
After the count, we tallied the results and provided our data to the North American Butterfly Association for inclusion into their nationwide database. Scientists and others use this data to understand more about butterfly populations, and the impacts of habitat losses and climate changes.
