Comments: The American Lady, Painted Lady, and the Red Admiral are all very familiar butterflies throughout
the United States, but despite their abundance and wide distribution there is still confusion about
their migration and ability to overwinter in the northern states such as Wisconsin.
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.
