Number: 350

Got home from vacation today with friends reporting observations of 15 on back yard flowers, 12 in a 2 acre prairie, similar density on a much larger private prairie, 200 on new england asters about noon south of town. We found an estimated 350 roosting in trees in the Monona Butterfly Gardens tonight. Observations show a nectaring shift from sedum to new england aster and zinnias. They have also been observed in large numbers sucking water and minerals from gravel roads and parking lots near the butterfly gardens
