Phoebis sennae, the cloudless sulphur, is a mid-sized butterfly in the family Pieridae found in the Americas. There are several similar species such as the clouded sulphur, the yellow angled-sulphur, which has angled wings, the statira sulphur, and other sulphurs, which are much smaller. The species name comes from the genus Senna to which many of the larval host plants belong.
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.
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.
Papilio multicaudata, the two-tailed swallowtail, is a species of the family Papilionidae found in western North America from British Columbia to Central America.
The black-headed grosbeak is a medium-sized, seed-eating bird in the family Cardinalidae. It is sometimes considered conspecific with the rose-breasted grosbeak with which it hybridizes on the American Great Plains.
Sphinx perelegans, commonly known as the elegant sphinx, is a species of hawkmoth described by Henry Edwards in 1874. It is a large gray moth native to western North America.
The gray hairstreak is also called the bean lycaenid or cotton square borer. It is a member of the Lycaenidae family, known as the gossamer-winged butterflies and the second-largest family of butterflies. It is one of the most common hairstreaks in North America, ranging over nearly the entire continent. It also occurs throughout Central America and in northern South America.
Adelpha californica, the California sister, is a species of butterfly in the family Nymphalidae. They are common in California, but can also be found in western Nevada and Oregon, as well as in northern Baja California. The upper surfaces of their wings are dark brown to black with wide cream white bands dissecting both wings and two orange patches near the tips of the forewings. The underside is variously colored with browns, blue, orange, and white. A. californica is unpalatable to predators and is part of a large mimicry complex.
The western pygmy blue is one of the smallest butterflies in the world and the smallest in North America. It has reached Hawaii, as well as the Persian Gulf, including Kuwait, eastern Saudi Arabia, Bahrain and the United Arab Emirates.
The eastern tailed-blue or eastern tailed blue, also known as Everes comyntas, is a common butterfly of eastern North America. It is a small butterfly that is distinguished from other blues in its range by the small thin tail.
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.
Euptoieta claudia, the variegated fritillary, is a North and South American butterfly in the family Nymphalidae. Even though the variegated fritillary has some very different characteristics from the Speyeria fritillaries, it is still closely related to them. Some of the differences are: variegated fritillaries have two or three broods per year vs. one per year in Speyeria; they are nomadic vs. sedentary; and they use a wide range of host plants vs. just violets. And because of their use of passionflowers as a host plant, variegated fritillaries also have taxonomic links to the heliconians. Their flight is low and swift, but even when resting or nectaring, this species is extremely difficult to approach, and, because of this, its genus name was taken from the Greek word euptoietos meaning "easily scared".
Chlosyne lacinia, the bordered patch or sunflower patch, is a North and South American butterfly in the family Nymphalidae.
Celastrina ladon, the spring azure or echo blue, is a butterfly of the family Lycaenidae. It is found in North America from Alaska and Canada south of the tundra, through most of the United States except the Texas coast, southern plain and peninsula Florida; south in the mountains to Colombia, also on Molokai island, Hawaii.
Limenitis weidemeyerii, or Weidemeyer's admiral, is a butterfly from the subfamily Nymphalinae, found in western North America.
Phyciodes mylitta, the Mylitta crescent or Mylitta crescentspot, is a butterfly of the family Nymphalidae. It is found in western North America.
Euphyes vestris, the dun skipper, sedge witch or dun sedge skipper, is a species of butterfly of the family Hesperiidae. It is found in North America from Nova Scotia west across southern Canada to southern Alberta, south to Florida, the Gulf Coast and eastern Texas. There are disjunct populations in the High Plains and Rocky Mountains and along the Pacific Coast.
Satyrium californica, the California hairstreak, is a butterfly of the family Lycaenidae. It is found from British Columbia south to southern California and east to Colorado.
Ochlodes sylvanoides, the woodland skipper, is a butterfly of the family Hesperiidae. It is found in North America from British Columbia south to southern California, east to Montana, Colorado and Arizona.
Heliopetes laviana, the Laviana white-skipper or Laviana skipper, is a butterfly in the family Hesperiidae. It is found from Argentina through Central America and northern Mexico to southern Texas. Strays can be found in southern Arizona and central and northern Texas. The habitat consists of edges of brushy areas, trails, roadsides, open woodland, thorn forest and streamsides.
