Number: 500

They have returned, so far maybe only around 500. Hope to see more tomorrow. All over the yard, in apple tree, maple tree, pines, etc. Clusters and clusters of them.

Editor's note: contacted observer for more details on this sighting

Roost formed on 9/13 around 6 pm.

I estimated the 500 by counting a large clump- that had about 50, there were two clumps together on the same branch, making about 100. I had 4 more of these double-clumps on trees not far from this first set (which was right outside my window).

I still have lots of flowers in bloom, and my property is nearly surrounded by a large field filled with goldenrod.

I am not sure of the overnight temperature, but we are starting to be in the mid to upper 50s overnight. It WAS windy. The clusters outside my window were moving a lot in the wind. I was worried for them. The other clusters had less impact from the wind.

Last year I believe I had THOUSANDS rest on grapevine that has grown over a bunch of smaller maples in a very sheltered spot. Far more than my report this year. I knew something was up when there were SO MANY butterflies in the sky, I had to go out and experience it. Walking around the yard I found the roost in a far corner, not visible from house. It was amazing. I had never seen anything like it! My neighbors are still mad I didn’t share it until a few days later. I am new to living in the country and just assumed it was a normal occurrence I was ignorant of. So I am looking for a repeat of that visit!
