Monarch PEAK Migration
Sightings report image

Date: 09/11/2020

Number: 800

Observed migration off and on from 09/11/2020-09/13/2020

We did not see a huge number of butterflies in one particular glance, but they were constant: one or two or small groups at a time. We sat on a second floor deck of the house for over an hour staring above us, in total shock and constant exclamation!!

They were all going in the same path, every day we saw them. We were right on the edge of Lake Michigan and the Monarchs were flying south, maybe a little southwest, heading toward the lake.

The number 800 is an estimate, the estimate being over the main two days we saw them, and that was really only a total of about two hours. (It was around 6:15-7:30 pm on 9/11 and 12:45pm-1:30 pm on 9/13).

The weather was around 60 degrees and mostly cloudy both days. The day in between was mostly rainy, so we were not looking for them, but did glance for a few minutes and it was not a lot.

They were just flying so fast. Once in a while you would see two of them fluttering/ playing together, but mostly they were on a mission! And they were high in the air, mostly above the tall house we were at.
