A very large butterfly with a wingspan of up to 5 7/8", the Tiger Swallowtail is one of the most striking of all of the North American butterflies.

Found east of the Rocky Mountains and the caterpillar eats the foliage of the wild cherry, birch, poplar, ash, and tulip trees.

If you look at the back wings of this species and see blue, you will know it is a female.

Wing span: 3 5/8 - 6 1/2 inches (9.2 - 16.5 cm).

Identification: Male is yellow with dark tiger stripes. Female has 2 forms: one yellow like the male and the other black with shadows of dark stripes. Hindwing of both female forms has many iridescent blue scales and an orange marginal spot. On the underside of forewing of both female forms the row of marginal spots has merged into a continuous band.

Life history: Males patrol for receptive females. Females lay eggs singly on host leaves. Caterpillars eat leaves and rest on silken mats in shelters of curled leaves. Chrysalids overwinter.

Flight: 3 flights from February-November in Deep South; 2 flights from May-September in north.

Caterpillar hosts: Leaves of various plants including wild cherry (Prunus), sweetbay (Magnolia), basswood (Tilia), tulip tree (Liriodendron), birch (Betula), ash (Fraxinus), cottonwood (Populus), mountain ash (Sorbus), and willow (Salix).

Adult food: Nectar of flowers from a variety of plants including wild cherry and lilac (Syringa vulgaris).

Habitat: Deciduous broadleaf woods, forest edges, river valleys, parks, and suburbs.

Range: Eastern North America from Ontario south to Gulf coast, west to Colorado plains and central Texas.

This butterfly is very common in the Eastern United States. Adult forms comes out mid to late summer. Tend to be solitary, moving over a large range, mainly searching trees and other plants for the right host to lay eggs. Comes to flowers of a wide variety. I have notice it feeding on petunias and joe pye weeds in my yard and a wide variety of butterfly flowers in public gardens. There are also a black phase - books said that only females can be in this phase - copy pipevine swallowtails pretty good - only faint marks can be seen - giving the butterfly a bit more lighter color appearance. Maybe 10 to 20% of all seemly pipevine swallowtail that we see are actually black phase of tiger swallowtail?

It really depends upon where you look to see seemingly pipevine swallowtails- Red spotted purples are very similar as are Diana fritillaries(though the Diana's are quite a bit larger and very rare in most places). As far as swallowtails the spicebush and black swallowtails are very similar as well. The pipevine swallowtails have a distinctive flight pattern and a very different color if you know what to look for. Net them and take a closer look! Here in places where Tiger swallowtails are common perhaps 80% of the black butterflys on red clover are tigers one of two percent are pipevines and the rest are other species of swallowtails with an occasional dark Danaid or Speyeria. Milkweed is the place for me to find pipevines and I see many spicebush swallowtails on wild mints.
