Today's Report Includes:


News from the Migration Trail

The leading edge of the migration is now approaching latitude 45 N. That’s exactly half way to the North Pole! How far north do you think the monarchs will travel? Where do you think they will stop and why?

Highlights this week:

  • The first monarch has been reported from Canada! Add the province of Ontario to the count, along with the state of Minnesota where a monarch was seen on May 16th. Here’ is the state/province count to date:
  • Also noteworthy this week were the reports of first monarch sightings in southern tier states such as Arkansas, Louisiana, Florida, Georgia and Oklahoma. People there usually see their first monarchs in lat March and April, not mid-May.

The Monarch Migration Continues...
We will continue to track the monarch migration through June, when the migration has spread throughout the breeding range. Hereafter, weekly updates will include migration maps and data only.

We Need Your Help: Please Report Your Sightings!
Even if monarchs have already been reported from your state or province, we want to know when you see YOUR first monarch.

Remember: We can’t track the migration without your help!
