Description

Family Papilionidae

'The Papilionidae belong to the Superfamily Papilionoidea, the true butterflies. Swallowtails are worldwide in distribution and comprise approximately 560 species. They are richest in the tropics, and their brilliant colors make them favorites of butterfly enthusiasts. Many swallowtail species, especially in the tropics, mimic other butterflies that are distasteful, while others are distasteful and cause birds and other vertebrate predators to regurgitate. Swallowtail adults are medium to large and may or may not have tails, while parnassian adults are medium, tailless, and have translucent wings. All adult parnassians and swallowtails have three pairs of walking legs , and adults of all species visit flowers for nectar.

Subfamily Papilioninae

Swallowtails are members of the Family Papilionidae. They comprise about 560 species, have a worldwide distribution, and are richest in the tropics. Many are brilliantly colored and are favorites of butterfly enthusiasts. Many species, especially those in the tropics, mimic other butterflies that are distasteful, while others are distasteful and cause birds and other vertebrate predators to regurgitate. Adults are medium to large, may or may not have tails, and have three pairs of walking legs . Adults of all species visit flowers for nectar. Males of most species patrol for mates, while males of one group (Black, Old World, Anise, and Indra Swallowtails) perch on hilltops or ridges instead of patrolling . Swallowtails lay globular eggs and overwinter as pupae. Some species spend more than one year in the pupal stage, likely to survive drought years when little caterpillar food is available. In arid areas, the Black, Anise, and Indra Swallowtails often display this strategy.

Physical Description

Species Papilio polyxenes

Upper surface of wings mostly black; on inner edge of hindwing is a black spot centered in larger orange spot. Male has yellow band near edge of wings; female has row of yellow spots. Female hindwing with iridescent blue band. In the Southwest, yellow forms predominate in the subspecies P. coloro. (ref. 105493)

Size/Age/Growth

Wing span : 3 1/4 - 4 1/4 inches (8 - 11 cm). (ref. 105493)

Habitat

Meadows, fields , farmland, gardens and watersides . Seldom found in woods or forests .

This species likes open country and is seldom seen in forests or even along forest edges. It prefers old fields, meadows, marshes, savannas , gardens, and other open places. (ref. 104719)

A variety of open areas including fields, suburbs, marshes, deserts, and roadsides. (ref. 105493)

Typically found at an altitude of 0 to 462 meters (0 to 1,516 feet).[2]

Biology

Diet

Foodplants are species in the umbel family , such as Queen Anne's-lace (Daucus carota); both native and introduced species are used. Adults nectar on many species, such as milkweeds. (ref. 104719)

Caterpillar hosts: Leaves of plants in the parsley family (Apiaceae) including Queen Anne's Lace, carrot, celery and dill. Sometimes plants in the citrus family (Rutaceae) are preferred. (ref. 105493)

Adult food: Nectar from flowers including red clover, milkweed, and thistles. (ref. 105493)

Reproduction

Eggs are yellow. Caterpillars range up to 2" long, white to green with black bands on each segment, with yellow or orange spots. Host plants include Queen Anne's Lace and other members of the carrot family as well as some members of the citrus family. 2 or 3 broods; February - November in south.

Behavior

Flight period: Mid-March to mid-October; rarely to early November. There are apparently three broods, but the species seems to have a nearly continuous flight period. In the Piedmont and Coastal Plain , abundance peaks in July and August. (ref. 104719)
