Papilio eurymedon, the pale swallowtail or pallid swallowtail, is a relatively common swallowtail butterfly found throughout much of the western North America. The species was first described by Hippolyte Lucas in 1852. It is found on the Pacific coast from northern Baja California to southernmost British Columbia, and inland to New Mexico and the Black Hills of South Dakota. It is present from the coast to western Montana, and from Wyoming to northern New Mexico. It is absent from most of Nevada and western Utah. It prefers open woodlands and forest clearings, especially near permanent bodies of water such as ponds, but also urban parks and is occasionally seen in suburban areas. Though not as common as the western tiger swallowtail, the pale swallowtail can be seen in large numbers at puddling parties where up to a dozen or more males may be gathered. There they join other species to sip water from damp soil to obtain nutrients for mating. Their appearance is quite similar to that of the western tiger swallowtail, except they are a white-cream colour or very pale yellow. Some pale swallowtails also have differing amounts of red-orange patches on the top of the wings just above the tail. There is a submarginal band on the bottom of the hindwings. Tiger stripes and borders are thicker than those of western tiger swallowtails. The wingspan is typically 3.5 to 4.5 inches (8.9 to 11.4 cm).

The pale swallowtail has a single brood throughout most of its range, but two or more along the Pacific Coast. Adults fly from April to October and are most common in May and July. Caterpillars enter their pupal stage in the fall and overwinter before emerging as adults. Eggs are laid singly on host plants which include members of the genus Ceanothus , including buckbrush, mountain balm, and mountain lilac, as well as red alder, ocean spray, bitter cherry, and serviceberry species. Caterpillars are plump green with a single yellow band behind the thorax. They have two eye-shaped spots on the upper thorax, which may help frighten predators. Like most swallowtails, they have a red wishbone-shaped organ called the osmeterium, which pops out from behind the head and releases a foul odour to warn off predators. Caterpillars turn brown just before the fifth moult. The pupa is brown and looks like a piece of bark. As they pupate, they face upright, secure the tip of the abdomen to a branch with a silk thread, and hang freely.

Males perch and patrol for receptive females. Females lay eggs singly on host plant leaves. Caterpillars feed on leaves and rest on silken mats in shelters of curled leaves. Pupae hibernate. [1]

<i>Papilio glaucus</i> Species of insect

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. The male is yellow with four black "tiger stripes" on each forewing. Females may be either yellow or black, making them dimorphic. The yellow morph is similar to the male, but with a conspicuous band of blue spots along the hindwing, while the dark morph is almost completely black.

<i>Papilio</i> Genus of butterflies

Papilio is a genus in the swallowtail butterfly family, Papilionidae, as well as the only representative of the tribe Papilionini. The word papilio is Latin for butterfly.

<span class="mw-page-title-main">Swallowtail butterfly</span> Butterflies of family Papilionidae

Swallowtail butterflies are large, colorful butterflies in the family Papilionidae, and include over 550 species. Though the majority are tropical, members of the family inhabit every continent except Antarctica. The family includes the largest butterflies in the world, the birdwing butterflies of the genus Ornithoptera.

<i>Papilio troilus</i> Species of butterfly

Papilio troilus, the spicebush swallowtail or green-clouded butterfly, is a common black swallowtail butterfly found in North America. It has two subspecies, Papilio troilus troilus and Papilio troilus ilioneus, the latter found mainly in the Florida peninsula. The spicebush swallowtail derives its name from its most common host plant, the spicebush, members of the genus Lindera.

<i>Papilio rutulus</i> Species of butterfly

Papilio rutulus, the western tiger swallowtail, is a swallowtail butterfly belonging to the Papilionidae family. The species was first described by Hippolyte Lucas in 1852.

<i>Papilio zelicaon</i> Species of butterfly

Papilio zelicaon, the anise swallowtail, is a common swallowtail butterfly of western North America. Both the upper and lower sides of its wings are black, but the upper wing has a broad yellow stripe across it, giving the butterfly an overall yellow appearance. There are striking blue spots on the rear edge of the rear wing, and the characteristic tails of the swallowtails. Its wingspan is 52–80 mm. Its body is somewhat shorter than the rather similar western tiger swallowtail, with which its range overlaps; it also lacks the black stripes, converging toward the tail, of the latter. There is a somewhat darker subspecies, P. z. nitra, which is rare throughout the range, though somewhat more often found at lower elevations.

<i>Papilio multicaudata</i> Species of butterfly

Papilio multicaudata, the two-tailed swallowtail, is a species of the family Papilionidae found in western North America from British Columbia to Central America.

<i>Eurytides marcellus</i> Species of butterfly

Eurytides marcellus, the zebra swallowtail, is a swallowtail butterfly native to the eastern United States and south-eastern Canada. It is the state butterfly of Tennessee. Its distinctive wing shape and long tails make it easy to identify, and its black-and-white-striped pattern is reminiscent of a zebra. The butterflies are closely associated with pawpaws, and are rarely found far from these trees. The green or black caterpillars feed on the leaves of various pawpaw species, while the adults feed on flower nectar and minerals from damp soil.

<i>Papilio machaon</i> Species of insect

Papilio machaon, the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail. It is the type species of the genus Papilio. This widespread species is found in much of the Palearctic and in North America.

<i>Papilio demoleus</i> Species of butterfly

Papilio demoleus is a common and widespread swallowtail butterfly. The butterfly is also known as the lime butterfly, lemon butterfly, lime swallowtail, and chequered swallowtail. These common names refer to their host plants, which are usually citrus species such as the cultivated lime. Unlike most swallowtail butterflies, it does not have a prominent tail. When the adult stage is taken into consideration, the lime swallowtail is the shortest-lived butterfly, with male adults dying after four days and females after a week. The butterfly is native to Asia and Australia, and can be considered an invasive pest in other parts of the world. The butterfly has spread to Hispaniola island in the Western Hemisphere, and to Mahé, Seychelles.

<i>Pachliopta aristolochiae</i> Species of butterfly

<i>Papilio cresphontes</i> Species of butterfly

The giant swallowtail is the largest butterfly in North America. It is abundant through many parts of eastern North America; populations from western North America and down into Panama are now considered to belong to a different species, Papilio rumiko. Though it is often valued in gardens for its striking appearance, its larval stage can be a serious pest to citrus farms, which has earned its caterpillars the names orange dog or orange puppy. The giant swallowtail caterpillars possess remarkable camouflage from predators by closely resembling bird droppings. They use this, along with their osmeteria, to defend against predators such as wasps, flies, and vertebrates.

<i>Papilio appalachiensis</i> Species of butterfly

Papilio appalachiensis, the Appalachian tiger swallowtail, is a species of swallowtail butterfly found in eastern North America, particularly in the Appalachian Mountains. It is a hybrid of another two Papilio species, Papilio canadensis and Papilio glaucus, with which it shares many characteristics. The butterflies are normally yellow and contain black patterns in their wings. Their wingspans range from 86 to 115 mm. The caterpillars range in color from green and yellow to orange and are ornamented with black specks that give them the appearance of a bird dropping, which is useful for camouflage, or a large eye, a form of mimicry that is also efficient for protection. This species is univoltine. Females lay their eggs in May.
