"Papilio glaucus," Wikipedia, the free encyclopedia. The eastern tiger swallowtail, is a species of butterfly native to eastern North America. It is one of the most familiar butterflies in the eastern United States, where it is common in many different habitats and travels as far North as Winnipeg Manitoba, Canada. P. glaucus is found in the eastern United States from southern Vermont to Florida west to eastern Texas and the Great Plains. It is common throughout its range, although is rarer in southern Florida and absent from the Florida Keys. In 1932, a single specimen was collected in County Wicklow, Ireland.
