This is my first attempt to send a picture with my roost sighting report so bear with me. The picture was the best I could do considering the strong south winds as this block of timber was loaded with 100s of Monarchs. I was unable to go back out towards sunset, but I've tagged Monarchs in this same area for the past three days as they've fed heavily on the adjoining fields of Maximillian sunflowers, goldenrod & smartweed.

That monarch roost was just across the Missouri River on the Missouri side from my home here in Atchison Kansas in a tract of river bottom timber that has been in the federal wetland reserve program for over 20 years. It was around 5:30pm on September 16th that I first observed the roost and I tagged monarchs there over the next two days (9/17-18). Those monarchs were feeding mainly on maximillian sunflowers, goldenrod, and pink smartweed in the adjoining wetland areas. I did my tagging around noon both days (9/17-18). Winds were very strong out of the south (the timber shielded them very well from it) with daytime temperatures in the low 90s and overnight temperatures in the upper 60s.

Editor’s note: Observer confirmed 9/16 is the night the roost formed.
