Migrating Monarchs

The leading edge of migration is still scattered between latitude 42-46°N. Activity remains high in the Upper Midwest and is picking up in Southern Ontario. Northern progress accelerated the most along the East Coast where monarchs are now venturing into New Hampshire, Maine, New Brunswick, and Nova Scotia. How far north will monarchs be next week? Explore our Monarch Adult (FIRST sighted) map and make a prediction.
