Butterfly sighting

Aug 2 2021

Scott and Ann Swengel

Location: Buena Vista Grassland
Portage County

We walked about 4 miles to survey 6 grassland plots and found Regal Fritillaries in 4 plots we hadn't surveyed in 2021 before today. Eight of the 14 Regals (11 males, 2 females, 1 unknown) were south of Lake Road in one plot grazed using specialized strategies the last 5+ years. Our observed Gray Copper flight period reached 41 days counting the start and end dates.
