"I saw three monarchs just driving home from work yesterday, so clearly a significant number arrived very recently," noted Aaron Brees of Polk City, Iowa on May 25th.

News: Here They Come
As predicted, south winds swept northward across the Great Plains for the past week, and monarchs sailed into their northern breeding grounds. People reported 57 first-of-year sightings, and four new states announced the monarch's arrival — North Dakota, Minnesota, Wisconsin, and Michigan. The long-awaited surge is now underway.

"At 4 pm I saw my first monarch of the year, riding a south wind and heading north. Very happy to see them here, where a lot of healthy milkweed awaits them," reported Chris Brown from Ramsey, MN.

Backyard Habitat
As butterflies burst onto the scene they found backyard habitat awaiting. With the monarch's plight in the news, people have stepped up their planting efforts, from countryside to cityscape.

"I was planting milkweed seeds in my backyard this morning when a monarch butterfly flew over the yard!" wrote Cindy Pringle from Tuscola, IL.
