Too many to count living in a small wooded area for 4 days now.

[Additional information contributed by observer, added by Journey North, 09/21/21]:

The butterflies hung out in our small forest area for about a week. It may have been longer, we don't go in the woods everyday. From Sept 8-15. We only went out in the evening once and saw them clumping together on branches (roosting?) The next day they were gone.

There is a good amount of weeds in the forest and the ditch along the road. I keep a few perennial beds. We are surrounded by soybean fields. But we mainly saw them on the trees in the woods.

Overnight temperatures and wind direction: Don't know. Comfortably warm. High 50s-60s?

Roosting on maple (silver?), black willow, a very old wild apple tree. Shielded by the other trees only, no buildings.

Didn't try to count them.

Photo attached, but not very good, there were more than the photos show.

Also, I was bike riding at Midewin Nationional Tallgrass Prairie that same week and their were a lot there too.
