Many tress with large clumps of 50+. Arrived at roost about 6am as sun was coming up. After about 30 minutes they started moving as the sun was warming them. The trees were on the edge of a large field with goldenrod where many of the butterflies would go to nectar on.
I was only able to stay for a little more than an hour. Large groups were still leaving the trees when I left. (My first roost...worst day ever to have early a.m. dentist appt!)
