Summer is Near
This is the final Monarch & Milkweed News Update for spring 2021. Thank you for following along and sharing your observations. Please continue to report observations of adult monarchs, eggs, larvae, and milkweed throughout the summer months. And stay tuned for Pollinator Week, Western monarch summer reports, and the International Monarch Monitoring Blitz.
Another Great Spring Season
The 2021 spring migration season is coming to an end. So far, Journey North volunteers have submitted over 7,850 observations of monarch butterflies, monarch eggs, monarch larvae, and milkweed. We hope these migration updates have provided you a sense of joy and wonder. Please know that your reports contribute valuable data and help efforts to protect monarchs throughout North America. Thank you for following along and sharing your observations.
Eastern Monarch Population
Monarchs continue to approach the northern limits of their breeding range. In last week’s update, there were no reports of monarchs in Vermont, Maine, New Brunswick, and Prince Edward Island. This week, monarchs have made good progress! Only Journey North volunteers in New Brunswick have yet to report first observations of monarchs. Up to this point, the northernmost report has come from Dauphin, Manitoba (latitude 51°N).
Ellie in Randolph Center, VT: “[Monarch Butterfly] in the milkweed patch.” (06/08/2021)

Connie in Hebbville, NS: “Mid-day, first monarch of 2021, a female, depositing eggs on plants.” (06/05/2021)

Western Monarch Population
Letter from Gail Morris: Western Monarch Spring Report #15
In Gail’s final report for spring, she provides an overview of the season and details where monarchs are being spotted out west. Gail writes, “From the data you’ve reported, it appears to show some monarchs stay in some parts of Southern California and others seem to move outward on their Spring Migration. Even with the low overwintering population, some have sailed inland and also to Northern California with reports now of monarchs entering Oregon and even Washington but without a photo verification … Southern Nevada and Utah also have now seen monarchs arrive and move on as has New Mexico. It’s been a busy three months! Soon, as we approach the Solstice in late June, monarch movement will stop as they navigate nearby breeding grounds rich with native milkweed in bloom.”
Stay tuned for Western monarch summer reports!
