The Viceroy is a mimic of the Monarch and can easily be confused with it, especially in flight. The Viceroy is smaller, is found along wetland areas where its host plants, willows, are found, and has a dark postmedian line on the hindwing that can be seen from above or below. This butterfly, like the Monarch, is also found commonly throughout Wisconsin.
