Actual size of largest O. alexandrae on record Winged Desire Of the planet’s roughly 20,000 species of butter- flies, swallowtails are especially intriguing to collectors. The more than 560 swallowtails include the world’s largest butterflies—birdwings—and some of the most expensive and threatened (five are shown here). They face a triple menace of habitat loss, climate change, and poaching. Thanks to conservation programs and anti-poaching laws, swallowtails are surviving despite a black market where prices start in the pennies and run into the thousands for protected species. Named after the Greek poet Homer. Featured on Jamaican postage stamps. Discovered in 1965; traders often mislabel this species to elude law enforcement. Named after the famed nat- uralist, who nearly fainted at first sight of its beauty.
