About the Eastern Tiger Swallowtail
Papilio glaucus, 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, ranging north to southern Ontario, Canada, and is common in many different habitats. It flies from spring until fall, during which it produces two to three broods. Adults feed on the nectar of many species of flowers, mostly from those of the families Apocynaceae, Asteraceae, and Fabaceae. P. glaucus has a wingspan measuring 7.9 to 14 cm (3.1 to 5.5 in). The male is yellow with four black "tiger stripes" on each forewing. Females may be either yellow or black, making the females dimorphic. The yellow morph has similar coloring to the male, but with a conspicuous band of blue spots along the hindwing; the dark morph is almost completely black.
The green eggs are laid singly on plants of the families Magnoliaceae and Rosaceae. Young caterpillars are brown and white; older ones are green with two black, yellow, and blue eyespots on the thorax. The caterpillar will turn brown prior to pupating. It will reach a length of 5.5 centimetres (2.2 in). The chrysalis varies from a whitish color to dark brown. Hibernation occurs in this stage in locations with cold winter months.
The eastern tiger swallowtail is the state butterfly of Alabama (as well as state mascot), Delaware, Georgia, North Carolina and South Carolina, and is the state insect of Virginia. Wikipedia →
