Butterfly sighting

Scott and Ann Swengel

Location: Port Wing bogs
Bayfield County

Bibon Lake Bog and Port Wing Boreal Forest State Natural Area west unit bog. We think that Bibon Lake is the phenologically slowest bog that we study in Wisconsin. Because we saw 22 Bog Coppers there today, this means that Bog and Dorcas Coppers are in main flight or later than main flight throughout northern Wisconsin now.
