Was very excited to see so many Monarchs resting in our trees today. Hadn't seen this many in 40 years.

We first noticed the roost at 3:30pm, they stayed overnight through the storm we had, but moved to the sunny side of the trees in the morning. The overnight temp was 56 and it was in the low 80s during the day. They may have been there earlier, but we weren't back in those trees earlier that day or the day prior. They seem to like s hedge apple tree, and the area is surrounded by soybeans. Not much nectar except for a few goldenrods, our butterfly bushes and a small butterfly garden we planted. Haven't seen them visiting flowers though. They were fairly protected in their location.

Editor’s note: Observer confirmed 9/18 is the night the roost formed.
