I went back to the prairie remnant where I saw some daytime roosts this afternoon. I observed 5 roosts this evening all in within 100 or so yards of each other. 2 roosts had about 100 each, 2 had about 70 each and the fifth roost had around 20 Monarchs. I left quite early and there was still Monarchs coming in. A couple of small roosts of about 5 each had also formed with a number still feeding on Blazing star. This remnant has plenty of nectar plants so Monarchs will often feed and stage here before heading south.
Conditions here this summer were about ideal and I felt we would have a good local Monarch production. It is exciting to see so many on the grassland and in the roosts today, all pristine and ready to travel.
