Monarch Butterflies roost though the state of Wisconsin in the fall of the year during their migration south. I was fortunate enough to get a call from Bruce that he had a tip on a roost location. There were numerous trees loaded up with the Monarch Butterflies at the location. To my knowledge, this morning the Monarch Butterflies had moved on. Maybe they were waiting for the rain to stop late last night and then get in on the more northern air flow to once again continue their journey migrating south. It was amazing to witness these butterflies in this form, a first time ever for me. Images were taken on September 6, 2018.
Binomial name: Danaus plexippus
Interesting note: Monarch Butterflies can fly up to 3,000 miles in their migration south and can fly 50-100 miles a day.
