Butterfly sighting

May 12 2022

Scott and Ann Swengel

Location: Barrens between Millston and Black River Falls.
Jackson County

Mostly sunny, 80-97 degrees F. We walked 9 miles in barrens sites, all but one of which has Frosted Elfin records: Dike 17, North Brockway East, several in the Bauer-Brockway area, Stanton Road, west of Hunter Haven Road, and 1 other area. All of the Henry's Elfins were that were 0.05-0.5 miles west of Brockway Road in about 6 different survey units. Butterflies seemed to shut down activity before 1 pm, presumably due to dessication. We saw no butterflies in the last 2.4 miles of surveying, when we were in the best Frosted Elfin sites we tried today.
