Butterflies and Moths of The Ridges

The Dorcas Copper butterfly, one of many butterflies in The Ridges Sanctuary.

The Ridges Sanctuary in Baileys Harbor continues its summer lecture series on July 29 with “Butterflies and Moths of The Ridges” with Tom Poklen as the featured speaker. The presentation begins at 7 pm at the Baileys Harbor Town Hall and is free and open to the public, though donations will be accepted.

With its incredible diversity of plant communities and habitats, The Ridges Sanctuary supports a diversity of butterfly species. A one-day survey done in 2005 documented 25 species in the sanctuary, although the number of species that use the area is undoubtedly much higher.

One of the species found in the Ridges is the Dorcas Copper, a butterfly listed as a “special concern” species in Wisconsin. This butterfly is one of many species that will be discussed by Poklen during the program.

“Lake Lessons,” sponsored by The Ridges Sanctuary, are held each Thursday through August 12. Upcoming programs include “Wisconsin Wildlife: A Status Update” on August 5 and “Mosquitoes: The Good, the Bad and the Ugly” on August 12.
