The eastern tiger swallowtail is one of the most impressive butterflies in the eastern United States. It was first recorded in 1587 when it was drawn by John White during Sir Walter Raleigh's third expedition to the new world. It was originally thought to have a range that included much of Canada but in 1991 the Canadian tiger swallowtail was separated into its own species.
Here in the northern part of its range the eastern tiger typically has two broods per year. Eggs are laid on a larval host plant, which includes wild cherry, Magnolia, tulip tree, birch, ash and willow trees. The caterpillars rest on silken mats on the top of the leaves. The eastern tiger over winters in its' pupae form, chrysalis.
