Number: 200

they were in our Maple trees and pine trees. We had a lot of them during August in our yard but on Tues evening the trees were full of them, Wednesday sept 4 they where all gone. about 10 years ago we used to get a few clusters of them and then nothing. This year was amazing.

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

The date of the first roost was Sept 3. Time was 6:00pm.

The only nectar source is golden rod but we do have other wild flowers.

We had a strong western wind and they were on the east side of large maples.

To determine the number, I counted from the picture posted. There were a lot more than that. The air was full of them.

My daughter was with me. NO CAMERA, unfortunately. We were awe struck. I think there was more than 200.

I checked Sept.4 around 6:00 pm and didn't see very many but last night (9/5) there were (I think) at least 50 flying around.

Strong Westerly winds but a bit warmer.

We have been saving all milkweed we could for about 3
years hoping it would bring some back. Wow! My daughter has a meadow that is full of it this year.
