The habitats of these butterflies include brushy fields, woodland edges, coastal dunes, and even suburban gardens (Tveten and Tveten 1996). They are not found in high elevations or altitudes because of the cool temperatures (Forestieno and Sbordoni 1998). (Forestieno and Sbordoni, 1998; Tveten and Tveten, 1996)
Long-tailed skippers have a broad head and a hairy body with tufts of hair at the base of their curved-tip antennae. The wingspan of these hairy butterflies is between 4 - 5.4 cm (Klots 1951). The top side ofis dark brown with lighter brown spots. Wing bases, the part of the wing attached to the body, on the top are an irridescent green. Undersides of the butterflies are a lighter brown with dark bands and spots.
Larvae are yellowish green with a black line down the dorsal side of the body. The head is maroon and black and there are yellow and orange/red side strips. The reddish black head is also accompanied by an orange or yellow spot on each side. The pupa of this species is a reddish-brown and is covered with a waxy whitish powder (Scott 1986). (Klots, 1951; Scott, 1986)
Females lay up to 20 eggs (commonly in clusters of 2-6) underneath the leaves of the host plant (Scott 1986). Eggs are cream to bluish-green and are hemispherical and finely sculpted (Forestieno and Sbordoni 1998). Once the larvae hatch, they eat the leaves from their nests made of rolled leaves and supportive silk strands. The pupa forms a cocoon out of bits of leaves and silk strands. The life cycle of the butterfly is about thirty days (Capinera 1996). (Capinera, 1996; Forestieno and Sbordoni, 1998)
Beyond choosing sites to lay eggs, butterflies offer no parental care.
Caterpillars live in rolled leaves that are supported with strands of silk (Tveten and Tveten 1996). This is the reason for their nickname of 'Bean Leaf Roller' or 'Roller Worm' (Klots 1951). The adults are known as erratic flyers as their flightpath is rapid and completely unpredictable. (Klots, 1951; Tveten and Tveten, 1996)
Males find potential mates through olfaction. (Tveten and Tveten, 1996)
The adult butterflies have no specific attraction to certain plants. As long as there is a flowering plant with nectar, the butterfly will stop frequently (Tventen and Tventen 1996).
Larvae are found on Leguminosae and Fabacceae (Neck 1996). Some examples of common larval plants are Pisum, Desmodium, Bauhinia, cultivated beans, and any other viney plants (Klots 1951). (Klots, 1951; Tveten and Tveten, 1996)
Adults pollinate many plant species, while larvae feed on many plant species.
Long-Tailed Skippers have no positive influence on humans.
Since this species lays its eggs under bean plants, it can have a devastating effect on bean crop yield (Scott 1986). Although it takes many larvae to make an impact on the yield, they are still considered pests of bean plants. In terms of biological control, these larvae are found to be preyed on by certain species of wasps and stink bugs. The beanleaf roller larvae can also be infected with a virus that can kill up to 50% of the population. Common insecticides are also effective on killing the larvae (Capinera 2001). (Capinera, 1996; Scott, 1986)
The butterfly and its habitat are not listed as threatened. The adaptation of theto suburban gardens exempts it from becoming threatened in its wild habitat.
Collectors are not fans of this butterfly because of the tendency of the wings to fold under at death so they are hard to display. The wing muscle of the live butterfly are very strong and are therefore hard to capture. The long tails are very fragile and easily broken (Forestieno and Sbordoni 1998). (Forestieno and Sbordoni, 1998)

having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
Found in coastal areas between 30 and 40 degrees latitude, in areas with a Mediterranean climate. Vegetation is dominated by stands of dense, spiny shrubs with tough (hard or waxy) evergreen leaves. May be maintained by periodic fire. In South America it includes the scrub ecotone between forest and paramo.
uses smells or other chemicals to communicate
animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature
union of egg and spermatozoan
an animal that mainly eats leaves.
forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality.
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.
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.

the area in which the animal is naturally found, the region in which it is endemic.
an animal that mainly eats nectar from flowers
reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body.
breeding is confined to a particular season

A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.
A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.
