The male is an iridescent blue-green with a dark background. The female is more subdued in color. They have a wingspan of about 5.5 inches (14 cm). Both have a long "swallowtail."

Classification: Family Uraniidae (swallowtail moths), Genus Urania, many species: U. riphaeus (from Madagascar, an island off the southeast coast of Africa), U. leilus (from Peru), U. fulgens (from Mexico, Belize), U. croesus (from Tanzania), U. sloanus (from Jamaica).


URQUHART, FRED A.

Dr. Fred A. Urquhart (1911- ) is a Canadian scientist who has studied butterflies (Monarchs in particular). Dr. Urquhart was the first person to tag a monarch butterfly, beginning in 1937. In 1975, Dr. Urquhart determined that some groups of monarchs overwinter in the transvolcanic mountains of Mexico, undertaking a migration of 2,000 miles that takes up to three generations to finish. Urquhart's collaborators included his wife Norah, and Cathy and Ken Brugger. For more infroamtion see Urquhart's book, "The Monarch Butterfly: International Traveler ."
