Neonympha mitchellii is an endangered species of nymphalid butterfly of the eastern United States. [3] There are two known subspecies: [3]
Recent discoveries since 1998 of populations in Alabama, Mississippi, and Virginia are being studied for taxonomic classification, and may be grouped with N. m. mitchellii or be described as new subspecies. [3]
All subspecies, including those newly discovered, are federally protected under the Endangered Species Act. [3]
Its larvae can feed upon the highly-invasive Japanese stilt grass Microstegium vimineum , so populations of this butterfly are potentially at risk from efforts to remove stilt grass. [6] [7] A butterfly of similar appearance, the Carolina satyr ( Hermeuptychia sosybius ), is also able to feed upon stilt grass. [8]
Both subspecies are small brown butterflies with a wingspan rage of 34–44 mm. [9] [10] The upper surfaces of their wings are unmarked, while the undersides of the wings have rows of round, yellow-ringed eyespots. [11] N. m. francisci is slightly darker, with more irregularly shaped eyespots. [11]
Their eggs are greenish white to cream, becoming tan as they age. [11] The larvae's dark head can be seen a day or two before hatching. [11] First instar larvae, 3–4 mm long, have dark brown bilobed heads, while four subsequent instars, 6–12 mm long, have green bilobed heads, and green bodies with raised white ridges along the sides. [3] [11]
The chrysalis are 10.5–15.5 mm long, suspended with the head down. [3] [11] It is a light lime green, with pale green or white speckling, and turns a medium brown about two days before eclosion. [3] [11]
The luna moth, also called the American moon moth, is a Nearctic moth in the family Saturniidae, subfamily Saturniinae, a group commonly named the giant silk moths.
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.
The meadow brown is a butterfly found in the Palearctic realm. Its range includes Europe south of 62°N, Russia eastwards to the Urals, Asia Minor, Iraq, Iran, North Africa and the Canary Islands. The larvae feed on grasses.
The Saint Francis's satyr is an endangered butterfly subspecies found only in the US state of North Carolina. First discovered in 1983, it was first described by David K. Parshall and Thomas W. Kral in 1989 and listed as federally endangered by the US Fish and Wildlife Service in 1994. It is a subspecies of N. mitchellii and is restricted to a single metapopulation on Fort Liberty military base in Hoke and Cumberland counties. The other subspecies, Mitchell's satyr, is also federally endangered.
The small blue is a Palearctic butterfly in the family Lycaenidae. Despite its common name, it is not particularly blue. The male has some bluish suffusion at the base of its upper wings but is mostly dark brown like the female. The species can live in colonies of up to several hundred and in its caterpillar stage is cannibalistic.
The Scotch argus is a butterfly of the family Nymphalidae. In spite of its English name argus, it is not a close relation of the brown argus nor the northern brown argus.
The grayling or rock grayling is a species in the brush-footed butterfly family Nymphalidae. Although found all over Europe, the grayling mostly inhabits coastal areas, with inland populations declining significantly in recent years. The grayling lives in dry and warm habitats with easy access to the sun, which helps them with body temperature regulation.
Eacles imperialis, the imperial moth, is a member of the family Saturniidae and subfamily Ceratocampinae. It is found mainly in the East of South America and North America, from the center of Argentina to south Canada. The species was first described by Dru Drury in 1773.
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.
Orsotriaena medus is a butterfly found in south Asia, southeast Asia, and Australia. It is the only species in the genus Orsotriaena, first described by Hans Daniel Johan Wallengren in 1858.
Microstegium vimineum, commonly known as Japanese stiltgrass, packing grass, or Nepalese browntop, is an annual grass that is common in a wide variety of habitats and is well adapted to low light levels. It has become an invasive species throughout parts of the world, most notably North America.
The common wood-nymph is a North American species of butterfly in the family Nymphalidae. It is also known as the wood-nymph, grayling, blue-eyed grayling, and the goggle eye.
Megisto cymela, the little wood satyr, is a butterfly species of the Satyrinae family that occurs in North America.
Dispar compacta, commonly known as the dispar skipper, barred skipper, or barred grass-skipper, is a species of butterfly in the family Hesperiidae. It was described by Arthur Gardiner Butler in 1882 as Telesto compacta and is endemic to eastern Australia.
Erikssonia edgei, commonly known as the Waterberg copper, tilodi copper or Edge's acraea copper, is an obligate myrmecophylous lycaenid butterfly, which is native to Limpopo, South Africa. The critically endangered butterfly occurs in high-altitude grasslands on sandy substrates, and has only been obtained from the type and one subsequent locality. The population at the type locality, a farm in the Waterberg, went extinct about 12 years after its 1980 discovery. It was afforded species status in 2010, when no extant populations were known. The status of two populations, discovered in 2013 at a private nature reserve to the southeast, remains indeterminate.
Cercyonis sthenele, the Great Basin wood-nymph, is a North American butterfly in the family Nymphalidae.
Hermeuptychia sosybius, the Carolina satyr, is a butterfly of the family Nymphalidae. It is found in the United States from southern New Jersey south along the coast to southern Florida, west to south-eastern Kansas, central Oklahoma and central Texas. It is also found in Mexico and Central America.
Euphyes dukesi, or Dukes' skipper, is a butterfly of the family Hesperiidae. It lives in the eastern United States and in a small portion of southern Ontario, Canada, in three distinct populations. Preferred habitats are shaded wetlands, with various species of sedge plants it uses as host plants for its larvae.
The Stygian ringlet is a butterfly belonging to the subfamily Satyrinae, the "browns", within the family Nymphalidae. It is found locally in the Alps on dry limestone slopes. It is very similar to the Styrian ringlet and has sometimes been included in that species.
Papilio rumiko is a species of swallowtail butterfly. It is found from the south-western United States, through Mexico, El Salvador, Honduras, Costa Rica to Panama. The northernmost record is north-eastern Colorado.
