First Fall Roost!
Every August, people in the north suddenly begin to report roosting monarchs. The butterflies cluster in trees to spend the night. This season's first fall roost was reported in Minnesota on August 11th:

"I noticed clusters of 10-15 monarchs flying and hovering in the trees in the back," wrote Mrs. Finley from Padua, MN. By August 24th the roost had grown to 500 monarchs! "I went out to greet my little friends and they flew overhead in an amazing burst of color."
