The distribution of L. p. americana is found from Ontario to Kansas eastward; L. p. arethusa occupies the northwest but most likely is not found in central Alaska; L. p. polaris inhabits the west Arctic and Scandanavia; and L. p. phlaeas is found in Europe, Asia, and Northern Africa. Some authors believe L. p. americana may have been introduced to North America from Scandanavia in colonial times. (Holland, 1931; Maynard, 1891; Opler and Krizek, 1984; Scott, 1986)is Holarctic, covering northern and central North America, Europe, Asia, and Northern Africa.
American coppers can be found in most disturbed areas including fields, sandy prairies, powerlines, waste places and rocky places in the Rockies, and alpine fell-fields in the Sierra Mountains and arctic tundra. (Glassberg, 1999; Scott, 1986; Shapiro, 1966)
Adult American coppers are one of the smallest coppers, with the average wing length 1.3 cm in males (range 1.2-1.4 cm) and 1.5 cm in females (range 1.3-1.6 cm). They have orange forewings with black spots and a dark outer wing margin, and a grayish upper hindwing with and orange border with a row of black spots. The undersurface of the forewing is pale orange with black spots, and the hindwing a powder white with black spots and orange band. (Opler and Krizek, 1984)
The eggs are greenish white, ribbed, and turn completely white as they age. (Scott, 1986)
Pupae of American Coppers are light brown with many dark colored dots. (Scott, 1986)
After the egg hatches, American copper larvae will mature in three weeks. Pupation occurs under shelter such as stones, logs, or boards. According to some authors, American coppers overwinter as a chrysalis, however Scott (1986) reports that half-grown larvae hibernate, with the diapause triggered by short photoperiod and low temperatures. Adults emerge in the springtime. (Maynard, 1891; Opler and Krizek, 1984; Scott, 1986; Weed, 1926)
Male American coppers perch on the tops of leaves and flowers in low spots, awaiting females to pass by. Alpine males will perch in nooks at the base of rocky slopes. The males differentiate the females by their wing pattern. (Scott, 1986)
These butterflies mate between early spring and fall. American coppers produce a single brood in the northern parts of their range, and may have up to three broods of eggs in the south.
Butteflies do not exhibit parental care.
In Japan, American coppers lived up to 14 days in the wild. If they overwinter, they can live almost a year. (Scott, 1986)
American coppers are active from early morning until dusk. They frequently sun themselves, resting on tall flowers such as daisies, yarrow (Achillea millifolium), and Queen Anne's Lace (Daucus carota). (Shapiro, 1966; Weed, 1926)
American coppers communicate visually, and use touch during courtship. (Scott, 1986)
American copper larvae are known to feed on docks (Rumex) including sheep sorrel (R. acetosella), curly dock (R. crispus), Oxyria digyna, and in Europe Polygonum, associated with R. alpestris. (Glassberg, 1999; Scott, 1986)
Adults eat the nectar of may species, including common buttercup (Ranunculus acris), clovers (Trifolium spp.), yarrow (Achillea millifolium), oxeye daisy (Chrysanthemum leucanthemum), butterflyweed (Asclepias tuberosa), alfalfa (Medicago sativa), blazing star (Liatris spicata), dwarf cinquefoil (Potentilla canadensis), wild strawberry (Frageria virginiana), and mountain mint (Pycnanthemum virginianum). (Iftner, et al., 1992; Opler and Krizek, 1984)
Predators of all life stages of butterflies include a variety of insect parasatoids. These wasps or flies will consume the body fluids first, and then eat the internal organs, ultimately killing the butterfly. Those wasps that lay eggs inside the host body include Ichneumonidae, Braconidae, Pteromalidae, Chalcidoidea, Encyrtidae, Eulophidae, Scelionidae, Trichogrammatidae, and others. Trichogrammatidae live inside the eggs, and are smaller than a pinhead. certain flies (Tachinidae, some Sarcophagida, etc.) produce large eggs and glue them onto the outside of the host. The hatching larvae then burrow into the butterfly larvae. Other flies will lays many small eggs directly on the larval hostplants, and these are ingested by the caterpillars as they feed.
Most predators of butterflies are other insects. Praying mantis, lacewings, ladybird beetles, assasin bugs, carabid beetles, spiders, ants, and wasps (Vespidae, Pompilidae, and others) prey upon the larvae. Adult butterflies are eaten by robber flies, ambush bugs, spiders, dragonflies, ants, wasps (Vespidae and Sphecidae), and tiger beetles. The sundew plant is known to catch some butterflies.
American coppers most likely serve as minor pollinators. They also serve as a food source for a variety of predators.
Butterfly watchers enjoy seeing these colorful butterflies, and as part of a larger community of butterfly species, attract ecotourist dollars.
There are no known adverse affects of American coppers on humans.
American coppers are stable across their range and are of no conservation concern at this time.
American Coppers are also known as little coppers and small coppers. L. p. feildeni hs been known as Feilden's copper, arctic copper, and tundra copper. L. p. arethusa is named Arethusa copper and American copper, and L. p. hypophlaeas has been called western American copper and American copper. Lastly, L. p. arctodon is known as beartooth copper. (Miller, 1992)has been called American copper, flame copper, small copper, copper butterfly and short-tailed copper.

used loosely to describe any group of organisms living together or in close proximity to each other - for example nesting shorebirds that live in large colonies. More specifically refers to a group of organisms in which members act as specialized subunits (a continuous, modular society) - as in clonal organisms.

a period of time when growth or development is suspended in insects and other invertebrates, it can usually only be ended the appropriate environmental stimulus.
humans benefit economically by promoting tourism that focuses on the appreciation of natural areas or animals. Ecotourism implies that there are existing programs that profit from the appreciation of natural areas or animals.

An animal that eats mainly plants or parts of plants.
having a body temperature that fluctuates with that of the immediate environment; having no mechanism or a poorly developed mechanism for regulating internal body temperature.

Found in northern North America and northern Europe or Asia.
fertilization takes place within the female's body
offspring are produced in more than one group (litters, clutches, etc.) and across multiple seasons (or other periods hospitable to reproduction). Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes).
A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.
