Location: Lake Superior coastal bogs
Most years Bog Coppers would still be pre-peak here on this date, but they are past peak in 2020. The two Port Wing bogs had a combined 67% as many Bog Copper sightings as on our July 4 survey, Bark Bay had 44% as many as on July 3, and we saw zero today at Lost Creek Bog, compared to 16 on July 4.
These sightings are submitted by butterfly enthusiasts across Wisconsin.
