The Eastern Tiger Swallowtail Butterfly (Papilionidae) can be found from Ontario, Canada, down to the Gulf states, and west to the Colorado plains. There are 10 swallowtail species in Florida. The most familiar is the yellow and black striped Eastern Tiger Swallowtail, which can be seen from the Georgia border south to the Big Cypress Swamp.
The Eastern Tiger Swallowtail has an average wingspan of 2 1/2 to 4 1/2 inches. They enjoy the nectar of many plants, including wild cherry, honeysuckle, lilac, Joe-Pye weed, azalea, and milkweed.
The swallowtail in the first picture is identified as a male because there is no blueish coloring in the hindwings. Although some females are melanic (dark-colored), the second picture is of the most common color seen on females.
An adult swallowtail’s lifespan is only about 2 weeks. They produce 2-3 broods a year in the south. Females lay a single egg on host leaves. Caterpillars will eat the leaves and rest on silken mats on the upper surface of the leaves. The caterpillar is brown and white when it is young, but it changes color as it grows older to green with orange and black false eyespots. The eyespots are thought to scare away predators.
