Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers, and the most recent analyses suggest it also contains the moth-butterflies. Butterfly fossils date to the Paleocene, about 56 million years ago.
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family. The family was created by William John Swainson in 1820.
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.
Zerene eurydice, the California dogface butterfly, belongs to the family Pieridae and is a member of a genus closely related to the genus Colias. A study that collected mitochondrial DNA from various Colias butterfly species found that Z. eurydice had decreased divergence from the ingroup, highlighting how closely related these two genera are. This species is endemic to California, and is California's state insect. The California dogface butterfly varies in its wing color and pattern.
Rudbeckia hirta, commonly called black-eyed Susan, is a North American flowering plant in the family Asteraceae, native to Eastern and Central North America and naturalized in the Western part of the continent as well as in China. It has now been found in all 10 Canadian Provinces and all 48 of the states in the contiguous United States.
Grass skippers or banded skippers are butterflies of the subfamily Hesperiinae, part of the skipper family, Hesperiidae. The subfamily was established by Pierre André Latreille in 1809.
Hyles gallii, the bedstraw hawk-moth or galium sphinx, is a moth of the family Sphingidae. The species was first described by S. A. von Rottemburg in 1775.
Mud-puddling, or simply puddling, is a behaviour most conspicuous in butterflies, but occurs in other animals as well, mainly insects; they seek out nutrients in certain moist substances such as rotting plant matter, mud and carrion and they suck up the fluid. Where the conditions are suitable, conspicuous insects such as butterflies commonly form aggregations on wet soil, dung or carrion. From the fluids they obtain salts and amino acids that play various roles in their physiology, ethology and ecology. This behaviour also has been seen in some other insects, notably the leafhoppers, e.g. the potato leafhopper, Empoasca fabae.
The purple-edged copper is a butterfly of the family Lycaenidae.
Enodia anthedon, the northern pearly-eye, is a butterfly species of the subfamily Satyrinae that occurs in North America, where it is found from central Saskatchewan and eastern Nebraska east to Nova Scotia, south to central Alabama and Mississippi.
Eurydice pulchra, the speckled sea louse, is a species of isopod crustacean found in the northeast Atlantic Ocean.
Satyrodes is a genus of Satyrinae butterflies that is native to North America.
Satyrodes appalachia, the Appalachian brown or woods eyed brown is a species of Satyrinae butterfly that is native to North America.
Westchester County, New York is located in southern New York, sharing its southern boundary with New York City and its northern border with Putnam County. It is bordered on the west side by the Hudson River and on the east side by the Long Island Sound and Fairfield County, Connecticut. The county has a total area of 500 square miles, of which 430 square miles is land and 69 square miles (14%) is water. It is an area rich in biodiversity with many parks and preserves. Literary environmental writer Alex Shoumatoff hailed Westchester County as the "most richly diversified deciduous forest in the world" in a 1978 The New Yorker profile, at the time estimating that it contained 4,200 species of plants.
Lethe appalachia, known generally as the Appalachian brown or Appalachian eyed brown, is a species of brush-footed butterfly in the family Nymphalidae. It is found in North America.
