Calephelis muticum, the swamp metalmark, is a butterfly species in the family Riodinidae.
Males have pointed forewings while the females tend to be slightly more rounded. Both sexes have bright red-brown wings which are lightly checkered. Wingspan is 2.4 to 3 cm. [1]
They have populations in the United States in southern Michigan, Ohio, Missouri, southern Wisconsin and northern Arkansas. There are also small populations in Iowa and Kentucky. They are most often seen in bogs, marshes, swamps and wet meadows. The species is endangered in Illinois. [2]
The eggs are laid singly on the underside of the host plant. Fourth and fifth stage caterpillars overwinter. In the Great Lakes region there is only one brood between June and August, while in the southern regions there are two broods between May and September.
Calephelis muticum is threatened by ongoing loss and degradation of habitat, invasive species, and pesticides. [3]
Apodemia mormo is a principally Nearctic butterfly in the family Riodinidae. It is a particularly fascinating species for ecological and evolutionary research, as evidenced by its shifting taxonomic classifications. Conflicting observations of host plants utilized, distinctive morphologies, and a wide range of occupied habitats have prompted investigation into several potential subspecies. To date, two genetic studies have been done on A. mormo, with analysis revealing that disjunct populations are genetically and phenotypically distinct. These studies support a potential need for refined taxonomies, although a larger body of data is required to make clear decisions.
The ringlet is a butterfly in the family Nymphalidae. It is only one of the numerous "ringlet" butterflies in the tribe Satyrini.
Packera obovata, commonly known as roundleaf ragwort, spoon-leaved ragwort, roundleaf groundsel, or squaw-weed, is an erect perennial herb in the Asteraceae (aster) family native to eastern North America. It was previously called Senecio obovatus. Basal and lower leaves are obovate with toothed margins, while upper leaves are pinnately divided. The ray flowers are yellow and the disk flowers orange-yellow, the inflorescences being held well above the foliage.
Apodemia mormo langei, the Lange's metalmark butterfly, is an endangered North American butterfly. It is a subspecies of the Mormon metalmark and belongs to the family Riodinidae. The butterfly is endemic to California, where it is known from one strip of riverbank in the San Francisco Bay Area. A 2008 count estimated the total remaining population at 131 individuals. Since 2011, this number has dropped to about 25–30.
Plebejus idas, the Idas blue or northern blue, is a butterfly of the family Lycaenidae. It belongs to the subfamily of Polyommatinae.

The crystal skipper is a species of butterfly in the family Hesperiidae that is found only along a 30-mile (50 km) stretch of barrier islands in North Carolina. The skipper was first discovered in 1978 and the paper describing it as a full species was published in 2015.
Calephelis nemesis is a butterfly in the family Riodinidae. It is found in the southern part of the United States and Mexico. Its habitats include chaparral canyons near rivers in arid areas, roads, and washes.
Calephelis perditalis, also known as the rounded metalmark or lost metalmark, is a species of butterfly in the family Riodinidae. It is found in Texas in the United States and Mexico, south to Venezuela. The species was first described by William Barnes and James Halliday McDunnough in 1918.
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.
Cirsium muticum, also known as swamp thistle, marsh thistle, dunce-nettle, or horsetops, is a North American species of plants in the family Asteraceae, native to central and eastern Canada and the central and eastern United States.
Calephelis borealis, commonly known as the northern metalmark, is a butterfly of the family Riodinidae. It ranges through western Connecticut south through west-central Pennsylvania; central Appalachians and Ohio River Valley. Isolated populations are also found in southwest Missouri and eastern Oklahoma. The habitat consists of open woodland streams near serpentine, shale or limestone barrens.
