NABA Memorial Day/Victoria Day Butterfly Counts

The NABA Memorial Day Count (in the United States) will be held May 27-29, 2017 and the Victoria Day Count (in Canada) will be held May 20-22, 2017.

These counts will give butterfly enthusiasts throughout the continent an opportunity to get out and enjoy butterflies while contributing to our growing knowledge of butterfly distributions, flight times, and abundance.

In contrast to the highly organized NABA 4th of July and 1st of July Butterfly Counts, the Memorial Day and Victoria Day Counts are free-form. All you need to do is to observe butterflies at one or more of your favorite butterflying localities (such as your own backyard) this coming Memorial Day or Victoria Day weekend and note what butterflies you’ve seen. There are no requirements regarding how much time or area you cover. Then go to the NABA Recent Sightings web site, sightings.naba.org, sign up for a free account and enter your sightings, filling in the location, date, and butterflies seen.

Because these counts will be taking place during a very different time of year than do the 4th of July and 1st of July counts, we can expect to see different populations of butterflies than those present for the July counts. Because the approach is different, maybe we’ll also see different populations of counters!

We hope that literally thousands of enthusiasts will have a great time outside and contribute to our knowledge of butterfly populations across the continent.
