There are about 600 species of butterflies found in the United States - though their numbers seem to be dwindling rapidly. In contrast we have roughly 12,000 species of moths! Since butterflies are diurnal people are quite familiar with them; but most moths only come out at night. Still, some of the most colorful Lepidoptera species are moths - the Cecropia, Luna, and Io are some that I've seen (though not all photographed) in Michigan.
