Thanks for visiting Wisconsin butterflies. Apart from the skipper butterflies, Wisconsin hosts around one hundred different butterfly species. That puts is at an average number in terms of butterfly diversity in US states.
Interestingly enough, Wisconsin is one of the few states that has not designated a state butterfly.
The first two pictures show an American Lady and Painted Lady butterfly. The white dot on the wing is the best field identification clue to distinguish the species.
It’s often feast for famine in Wisconsin Painted Lady and American Lady visits. Originally it was thought that because they were among the first butterflies to appear in spring they overwintered in the state.

For Wisconsin butterfly enthusiasts the presence of Olympia White butterflies announces the start of another butterfly season. They are the smallest of the white butterflies and have a short spring season.

When it comes to Wisconsin blue butterflies, the Karner Blue, as subspecies of the Melissa Blue, receives most of the attention. It is listed as an endangered species and habitat in central Wisconsin is put aside to insure it’s survival.
The large number of blue butterfly species is a bit misleading. The Eastern Tailed-Blue and the Azures are the most common species. The remainder of the blue butterfly species have limited ranges in the state or are considered as stray visitors.
Wisconsin is also a great destination for copper butterfly viewing, especially in the north. The picture shows an American Copper.

With the exception of the border areas along Lake Michigan, it’s fairly common late spring through early fall.

Brush Footed Butterflies

Along with the Lady butterflies already mentioned, Wisconsin also hosts a wide variety of brush-footed butterflies. The picture shows a Goatweed Leafwing, the most common of the Leafwing species in the United States. It could also be captioned, Have you seen this butterfly? There was an old report of its presence in the state. No reports of its presence have been recorded in the past one hundred years. Perhaps a changing climate will change Wisconsin butterfly history.
Medium to large size, along with orange patterned wings often serve as good identification tips for brush-footed butterflies. The long nose like appendage on the American Snout serves as another good identification clue. While they are common in the south parts of the United States, they reaches the northern part of its range in southern Wisconsin.
Previously common in it’s tallgrass prairie habitat, it’s endangered in Wisconsin and found in the prairie habitat.of a string of south-central counties. The enlarged black mark on the wings serves as a good identification clue.
