They're certainly the kings of our hearts. Kids learn about them in school. They're the official insect or butterfly of seven U.S. states. I saw a scantily-clad version of one this Halloween, complete with fairly accurate wing patterns. (But no compound eyes or proboscis! Whyever not?) People love monarch butterflies. In fact, Americans love monarch butterflies so much that in a new survey, they indicated that, as a country, they'd be willing to pay more than $4 billion for their conservation.
