Four species of (Bartlett, 2012)are found in North America, but this number is not agreed upon by authorities. The number may be interpreted as few as two species or as many as five or six. Due to species hybridization, it is difficult to define the number of species. Some species tend to hybridize where their ranges overlap. This may lead to entire populations of hybrid butterflies in these “blend” zones. In Eurasia, there are one or more species that are distinct from those found in North America.
Species of the genus (Bartlett, 2012), known as admiral butterflies, are found throughout North America and temperate Eurasia.
Admiral butterflies are found in sunny areas of wooded areas like forests and mountains. Caterpillars of this genus are most often found near their host plants. (Bartlett, 2012)
American species may be classified into a genus called Basilarchia in some literature. (Bartlett, 2012)
Admiral butterflies are large butterflies that don’t have tails nor additional appendages on their wings. Coloring between species of this genus is distinct. They may be confused with the species queens, members of the genera sisters and monarchs, and the family called swallowtails. (Bartlett, 2012)
The caterpillars of the various species look very similar and can be hard to differentiate. Caterpillars look rough and have large bumps. They have two large bumpy horns. Resembling bird droppings, caterpillars are dark brown or green in color. They may have spots of white or cream color. Swallowtail caterpillars may look similar, but they lack the horns. (Bartlett, 2012)
Admiral butterflies, like other butterflies, undergo complete metamorphosis. Members of this genus overwinter as larvae. They build hibernaculum, which is like a cocoon made from part of a rolled leaf. (Bartlett, 2012)
Admirals breed seasonally and use sexual reproduction. Females lay eggs. (Bartlett, 2012)
Most adults live from late spring to early summer. They produce one generation per year. In the south, multiple generations may occur. Members of this genus overwinter as larvae. (Bartlett, 2012)
Admiral butterflies communicate through visual and chemical manners. They utilize vision and chemical methods for perception.
Larvae are laid on and feed on host plants. They prefer members of the family Salicaceae, such as poplars and willows. They may also consume members of the family Rosaceae, including apple, serviceberry, and cherry. Occasionally, they have been observed feeding on alder, birch, oak, lindens, and vaccinium. Adults feed on nectar. (Bartlett, 2012)
Some species of admiral butterflies utilize Batesian mimicry. Viceroy butterflies (Limenitis archippus) are well-known mimics of monarch butterflies. Red-spotted purple or white admirals (Limenitis arthemis) are mimics of pipevine swallowtails. Monarch butterflies and pipevine swallowtails are unpalatable for predators. Members of this genus are eaten by predatory birds like blue jays (Platt, et al., 1971)
Adult admiral butterflies are pollinators that feed on nectar. Some species of this genus are mimics of unpalatable butterflies. Caterpillars feed on the host plants on which they are laid. (Bartlett, 2012; Porter, 1989)
Adult admiral butterflies are pollinators.

An animal that eats mainly plants or parts of plants.
fertilization takes place within the female's body
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.
This terrestrial biome includes summits of high mountains, either without vegetation or covered by low, tundra-like vegetation.
