Beginning Aug 7, 2020 I began noticing a big increase in the numbers of monarchs feeding in my 4 acre prairie, at my home.They preferred rough blazing star (liatris), stiff goldenrod, iron weed, yellow coneflower. Friday Aug 28 they started overnight roosting. They formed clusters in mature red oaks and white pine, 20-30 individuals in a cluster. This roosting continued each evening through Sept 3 when weather was windy NW15-25 and temps in low 50s. My habitat is 6 acres red oak and boxelder, 4 acres restored prairie and 10 acres open field (brome). Two small ponds within the prairie. This is the third year for a roost 1918, 2019, 2020. The largest numbers was in 2018, hundreds in 10-20 clusters. Smaller numbers in 2019 and 2020. HEAVEN!!
