The Jutta Arctic appears to be the most widely distributed of all the bog species in Wisconsin. The photos to the right were my first Jutta Arctic’s that I ever saw. I had been to Glocke Lake in Oconto County in 2004 and found Bog Coppers and thought that it looked like a potential site for other bog butterflies. I was very pleased to find Bog Fritillaries, but I got very excited when I saw the Jutta Arctics slowly working their way through the brush at the edge of the floating sphagnum mat. I saw two individuals and chased them around for about 20 minutes before I was able to get these photos.

Identifying characteristics: Below, the wings are mottled with various shades of brown and white. In the forewing there is a large brown area with a single eyespot, which may or not be visible. Above, which normally is not seen, is orange brown with a lighter orange area that includes a variety of eyespots on both the forewing and hindwing.

Similar species: The Chryxus Arctic does look somewhat similar but flies is a very different habitat and these species are unlikely to be seen together. In addition the Jutta is larger, has the lighter areas above that include the eyespots, and does not have a median line on the forewing below that has a has a pointed extension towards under the eyespot.

Habitat: Bogs and bog edges.

Flight: Seen from mid-May through mid-June.

Abundance: This is a seldom-encountered species that is rarely seen in significant numbers.
