Monarch Fall Roost
Sightings report image

Date: 09/29/2020

Number: 150

There were too many to count & it was getting dark when I found them, so photos aren't great. I have a video. They were all over a cedar tree & a post oak growing next to each other.

Roost first formed: 09/29/2020 – It was only for 1 night

Estimation method: Honestly, I don’t know. It looked like hundreds, but I didn’t want to exaggerate. I’ve never encountered a roost before & it was getting dark. There could have been up to 300, would be my guess.

Nectar sources nearby: There’s a large area of Hardy Ageratum on our property, plus butterfly bushes, Lantana and some Milkweed.

Shielded from the wind: YES!

Postscript note: it was a total surprise to encounter them roosting on the corner of our property. I felt so honored! Sadly, most of them moved on the next day & only a handful stayed. Today (Oct 2nd) we had a little push of winds from the north again & there seem to be more Monarchs showing up, but nowhere near what we had on Sept 29th.
