Number: 200

The numbers increased today (9/6). We have had storms the last 2 days but early this morning around 9:00, I photographed more groups gathering in our Silver Maple trees. I have also noted black moths that seems to be mixing in with the group. I would say there was probably 200 or more butterflies today.

Editor's note: We've re-dated this report from 9/06 to 9/05, the night the roost formed.
