Migrating Monarchs

The leading edge of monarch migration from the Midwest to the Mid-Atlantic still is hovering around latitude 40-42°N, though a few early observations have been recorded around 44-45°N. Along the East Coast, monarchs are making slow progress northward, with a few reports coming in as far north as Massachusetts:

Migration is moving at a brisk pace. Monarchs have now been reported as far north as New Brunswick, Canada. Activity will only increase over the coming weeks. Report your monarch observations to Journey North.
