First monarchs that I’ve observed in an annual roosting location near Tobermory, Ontario, Canada. They’ve crossed Lake Huron by island hopping and are resting/fuelling up for the next leg of the journey down the Huron shoreline to Point Pelee on Lake Erie - about 450km. Maybe 200 butterflies tonight, some nights this spot will hold thousands!
