Wisconsin DNR: Monarchs Arriving In Our State

Posted on 5-27-2021

Monarchs are arriving! While colder weather and unfavorable winds this spring delayed the arrival of monarchs, Wisconsinites are now reporting seeing these iconic beauties.

Wisconsin is in the core breeding ground for the eastern migratory population of monarchs. The state’s milkweed feeds and produces several generations each spring and summer before a final wave gorges itself on wildflower nectar and embarks on a 1,700-mile journey to central Mexico where they overwinter.

They begin migrating north in spring, and get as far as northern Mexico and the southern United States before laying eggs and dying. Their offspring take up the journey, and it is mostly this generation that reaches Wisconsin and lays their eggs, starting the cycle again.  

Thirty Years Of Watching, Waiting And Feeding Monarchs

Judy Cardin and Robert Plamann of Madison are among the many Wisconsinites who eagerly await the monarchs’ arrival. The couple have converted much of their front yard to a pollinator garden, and grow several milkweed species for monarchs.

“Bob and I have been looking for our first monarch this year, and at sunset on May 17 he spotted and photographed this weary traveler resting at Badger Prairie County Park,” said Judy.

She submitted their report and above photo to Journey North, a citizen science program based at the University of Wisconsin-Madison Arboretum whose online platform allows people to register and report observances of butterflies, birds and other nature. On May 22nd, the couple saw a monarch on milkweed in their yard.

“We have been entranced with the complex life cycle of Monarchs since we raised a tiny monarch caterpillar to adulthood almost 30 years ago with our 5-year-old son,” Judy said. “The three of us watched the monarch fly out of our son’s second story window with a sense of awe. I can still see it in my mind as I write this.
