Anartia jatrophae are very common in Central America and the Caribbean, as well as southern Texas and Florida. Small numbers can also be found in North Carolina, Missouri, Nebraska, and Kansas. (Emmit, 1999; Struttmann, 2004)
White peacock butterflies are commonly found in warm, open, weedy areas such as fields or parks where water is abundant -usually in the form of a pond or stream. Adult butterflies are often seen along roadside ditches where host plants are abundant. (Floridata, 2001; Struttmann, 2004)
The eggs of this species are small and green and found on the underside of host plant (Bacopa monniera) leaves. Caterpillars are black with silver or white dots and branched spines. The chrysalis is light green with small black dots. The upper side of the adult butterfly is white and contains a round black spot with a light-to-dark brown crescent-shaped trim on forewing. The hindwing has two spots similar to those on the forewing and is trimmed with the same crescent trim in brown to orange. The two front legs are non-functioning, giving the appearance of only four legs- characteristic of all members of the Nymphalidae family. In dry or winter seasons, the White Peacock becomes paler and larger. (Floridata, 2001; Struttmann, 2004)
Mature adults lay eggs on host plants. These eggs hatch 3-10 days later and the caterpillars live and feed on the host plant. The caterpillar transforms during the chrysalis stage into the adult butterfly form, completing holometablous metamorphosis. (Floridata, 2001; Hickman, et al., 1995)
Male white Peacocks perch or patrol in areas with an abundance of host plants and wait for a female. Males are very territorial and defends host plant territory from other species. It is still unclear if females mate more than once in their lifetime. (Lederhouse, et al., December 21, 1991)
Reproduction consists of a male seeking out a female. The male deposits a spermatophore into the female during copulation. Eggs are laid singly near or on the underside of leaves of the host plant Bacopa monniera. (Hickman, et al., 1995; Lederhouse, et al., December 21, 1991)
There is no evidence that parental care is given after eggs hatch.
Males display a unique territorial behavior. Males stake out a territory, typically 15 meters in diameter, that contains larval host plants. Males perch in this area and aggressively protect it from other insects and other male white peacocks. (Lederhouse, et al., December 21, 1991; Struttmann, 2004)
Like all butterflies, the White Peacock uses a number of sense organs including ocelli, and tympanic organs that detect vibrations. The also use pheromones when seeking a mate. (Hickman, et al., 1995)
Caterpillars require Bacopa monniera as a food source. As adults, white peacock butterflies feed on shepherd's needle, white hyssop, matchheads, wild Petunias, cordia, casearia and composites. (Lederhouse, et al., December 21, 1991; Struttmann, 2004)
The white peacock butterfly has fast, erratic flight that makes it difficult to attack. (Floridata, 2001)
Like many other butterflies the white peacock acts as a pollinator of various species of flowering plants including white hyssop, matchheads, and wild petunias. (Floridata, 2001)
There is no evidence that this species benefits humans other than providing research and education opportunities.
There is no evidence this species adversely affects humans.
Currently, there is no evidence that this species' numbers are threatened but it is on continual watch. (Cowley, 1997)

uses sound to communicate
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.
uses smells or other chemicals to communicate
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.
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.
chemicals released into air or water that are detected by and responded to by other animals of the same species
having more than one female as a mate at one time
Referring to something living or located adjacent to a waterbody (usually, but not always, a river or stream).
scrub forests develop in areas that experience dry seasons.
reproduction that includes combining the genetic contribution of two individuals, a male and a female

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.
