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:

Moving Northward
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.
Western Monarchs Update
Warming temperatures and fair skies helped increase the number of monarch sightings this week, especially in California. This is a trying time when many overwintering monarchs are reaching the end of their life but their offspring are often hidden as immatures – eggs, larvae, or pupae - on milkweed or nearby plants.
