The Oregon swallowtail (Papilio machaon oregonius, sometimes classified as Papilio oregonius or Papilio bairdii oregonius [1] ) is a subspecies of swallowtail butterfly native to the United States of America, Oregon, Washington, and Idaho and south-central British Columbia in Canada. [2] In 1976, it became one of the first four butterflies that the United States Postal Service placed on a U.S. stamp. [3]

The Oregon swallowtail was declared the state insect of Oregon in 1979 by the Legislative Assembly. [4] [5]

Description

The adult Oregon swallowtail has a yellow abdomen with black lines. It has a wingspan of 2.5 inches (6.4 cm) to 4 inches (10 cm). Its wings have concave spots that are scalloped inwards with a reddish-orange eyespot along the lower border, similar to, but smaller than, the eyespot of the common Old World swallowtail. The yellow markings on the wings of the Oregon swallowtail are also brighter than the common swallowtail. It has a tail characteristic of all swallowtail butterflies. The caterpillar is black with yellow markings. [6] [7]

It reproduces twice a year, and can be seen flying from April to September. The butterflies seen toward the beginning of the year are lighter in color than those seen later and blend well with the color of early plants. [8]

Range and habitat

The range of the Oregon swallowtail is from southern British Columbia, eastern Washington and Oregon, to Idaho and western Montana, primarily in the lower sagebrush canyons of the Columbia River and many of its tributaries. [8] In its caterpillar (larva) stage, it feeds on tarragon sagebrush. As an adult, it eats flower nectar, preferring thistles, balsamroot, and phlox. Chrysalids of this subspecies can overwinter. [2] [9]

A recommended viewing spot is along the banks of the Columbia River at Vantage, Washington, where Interstate 90 crosses the river. [10]

U.S. Postal Service stamp

On June 6, 1977, the United States Postal Service released sets of four 13-cent stamps illustrating American butterflies, including the Oregon swallowtail. Shortly thereafter, the butterfly was chosen as Oregon's state insect. [8]

<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, where it is common in many different habitats and travels as far North as Winnipeg Manitoba, Canada. It flies from spring then falls, 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.

Swallowtail butterfly 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 polyxenes</i> Species of insect

Papilio polyxenes, the (eastern) black swallowtail, American swallowtail or parsnip swallowtail, is a butterfly found throughout much of North America. It is the state butterfly of Oklahoma and New Jersey. An extremely similar-appearing species, Papilio joanae, occurs in the Ozark Mountains region, but it appears to be closely related to Papilio machaon, rather than P. polyxenes. The species is named after the figure in Greek mythology, Polyxena, who was the youngest daughter of King Priam of Troy. Its caterpillar is called the parsley worm because the caterpillar feeds on parsley.

<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 homerus</i> Species of butterfly

Papilio homerus, commonly known as the Homerus swallowtail or Jamaican swallowtail, is the largest butterfly species in the Western Hemisphere. The species is endangered and faces a potentially bleak future. Only two small populations of the Homerus swallowtail remain in a fraction of their original environment. It is endemic to Jamaica where the butterfly simultaneously serves as an icon of national pride and a need for conservation efforts. Over the past half century, the Jamaican swallowtail has been featured on various postal stamps and the Jamaican $1000 bill. In the face of rapid habitat destruction from human disruption and illegal collecting, the Jamaican swallowtail is listed on the Threatened Swallowtail Butterflies of the World by the International Union for Conservation of Nature and is protected under international and national level legislation.

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.
