throughout Wisconsin except for the northernmost counties, and is common in the southern
counties. It is found in moister habitats than the American Copper, and edges of wetland areas are
prime spots for this showy butterfly. The butterfly is often found perching on vegetationw hen
good nectar sources like Swamp Milkweed are available.
Caterpillars come in many colors, shapes, and sizes. Some caterpillars are quite hairy,
while others are smooth. Despite differences between species, though, all caterpillars
share certain morphological features.
