Eumaeus atala, also known as the Atala butterfly or coontie hairstreak, is a small colorful butterfly in the family Lycaenidae. It is found in southeastern Florida (including the Florida Keys) in the United States, Cuba, the Bahamas, and the Cayman Islands in the West Indies. Its coloration and habits are unique among butterflies within its range.
The species was first described by the Cuban zoologist Felipe Poey. He named the butterfly for Atala, the Native American heroine of an 1801 French novella ( Atala, ou Les Amours de deux sauvages dans le desert or in English: "Atala, or the Loves of two Indian savages in the desert") of the same name that was written by Chateaubriand.
Throughout its range, the larvae feed on a native cycad, Zamia integrifolia (commonly called "coontie palm" or "arrowhead"), as well as Zamia pumila and other exotic ornamental cycads. In Cuba, the introduced cycad Cycas revoluta also is eaten by this species.
Adult butterflies take flower nectar and sometimes roost in trees. Adults fly through much of the year. The natural habitat is open brushy areas and tropical hammocks, often in pine woodlands. Many populations now exist in suburban areas containing ornamental cycads. Males keep close to a site with host plants, often forming small colonies of a few individuals. The females, however, may disperse in search of more hosts.
The Atala butterfly is a great example of aposematic (warning) coloration throughout its life cycle. The brightly colored larva or caterpillar feeds on cycads that contain a toxic secondary plant chemical (cycasin) that it retains in its body for life. Birds, lizards, and other animals may attempt to prey on the larvae, pupae, and adults, but find them distasteful and learn to avoid these brightly patterned insects.
The butterfly's flight is slow, unlike the swift, erratic flight of many other Lycaenidae.
Like many Lepidoptera, male atalas have hair-pencils (coremata) on their abdomens used in courtship; the male hovers in front of the female, wafting pheromones exuded from the pencils in her direction. Eggs are laid in clusters of 10-50 on the leaf tips of the host plant. Larvae feed on the leaves. Pupation is usually completed on the host plant.
The United States population of the species was restricted to Florida and at one time, was believed to have become extirpated due to overharvesting of its host plant, the coontie palm. It was not collected in Florida from 1937 until 1959. In Palm Springs, Florida, the G-Star School of the Arts has been contributing to the growth of local population numbers. [2] The Atala butterfly is now extremely common locally in southeast Florida, having rebounded to the extent of almost being considered a pest for eating ornamental cycads planted in suburban areas as native plants are being chosen for landscaping.
Papilio troilus, the spicebush swallowtail or green-clouded butterfly, is a common black swallowtail butterfly found in North America. It has two subspecies, Papilio troilus troilus and Papilio troilus ilioneus, the latter found mainly in the Florida peninsula. The spicebush swallowtail derives its name from its most common host plant, the spicebush, members of the genus Lindera.
Lycaenidae is the second-largest family of butterflies, with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species.
The great purple hairstreak, also called the great blue hairstreak, is a common gossamer-winged butterfly species in parts of the United States. It is actually a Neotropical species; its North American range only includes the warm-temperate and subtropical parts of that continent, and it ranges southwards almost to the Isthmus of Panama. The type specimen, however, was shipped to Europe from the Colony of Virginia, probably around the time of the United States Declaration of Independence.
Zamia furfuracea is a species of cycad endemic to southeastern Veracruz state in eastern Mexico.
Zamia pumila, commonly known as guáyara in Spanish, is a small, tough, woody cycad native to the Greater Antilles. Z. pumila was the first species described for the genus and, therefore, is the type species for the genus Zamia and the family Zamiaceae.
Zamia is a genus of cycad of the family Zamiaceae, native to North America from the United States throughout the West Indies, Central America, and South America as far south as Bolivia. The genus is considered to be the most ecologically and morphologically diverse of the cycads, and is estimated to have originated about 68.3 million years ago.
Dryas iulia, commonly called the Julia butterfly, Julia heliconian, the flame, or flambeau, is a species of brush-footed butterfly. The sole representative of its genus Dryas, it is native from Brazil to southern Texas and Florida, and in summer can sometimes be found as far north as eastern Nebraska. Over 15 subspecies have been described.
Belidae is a family of weevils, called belids or primitive weevils because they have straight antennae, unlike the "true weevils" or Curculionidae which have geniculate (elbowed) antennae. They are sometimes known as "cycad weevils", but this properly refers to a few species from the genera Parallocorynus and Rhopalotria.
The queen butterfly is a North and South American butterfly in the family Nymphalidae with a wingspan of 80–85 mm. It is orange or brown with black wing borders and small white forewing spots on its dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests.
Sphinx franckii, or Franck's sphinx moth is a moth in the family Sphingidae. The species was first described by Berthold Neumoegen in 1893. It is known from lowland deciduous woodland in the eastern United States but also suburban areas where lilacs are planted, ranging from New York to northern Florida east to Missouri and Louisiana.
Anartia fatima, the banded peacock, is a butterfly in the family Nymphalidae. It is commonly found in south Texas, Mexico, and Central America but most studied in Costa Rica. This butterfly prefers subtropical climates and moist areas, such as near rivers. It spends much of its time in second-growth woodlands.
The giant swallowtail is the largest butterfly in North America. It is abundant through many parts of eastern North America; populations from western North America and down into Panama are now considered to belong to a different species, Papilio rumiko. Though it is often valued in gardens for its striking appearance, its larval stage can be a serious pest to citrus farms, which has earned its caterpillars the names orange dog or orange puppy. The giant swallowtail caterpillars possess remarkable camouflage from predators by closely resembling bird droppings. They use this, along with their osmeteria, to defend against predators such as wasps, flies, and vertebrates.
Smith's blue butterfly, Euphilotes enoptes smithi, is a subspecies of butterfly in the family Lycaenidae. This federally listed endangered subspecies of Euphilotes enoptes occurs in fragmented populations along the Central Coast of California, primarily associated with sand dune habitat in one case with a dune-based Maritime Coast Range Ponderosa Pine forest in the Carbonera Creek watershed in Santa Cruz County. The range of E. e. smithi is from Monterey Bay south to Punta Gorda.
The variable checkerspot or Chalcedon checkerspot is a butterfly in the family Nymphalidae. It is found in western North America, where its range stretches from Alaska in the north to Baja California in the south and extends east through the Rocky Mountains into Colorado, Montana, New Mexico and Wyoming. The butterfly is usually brown or black with extensive white and yellow checkering and some red coloration on the dorsal wing. Adult wingspan is 3.2–5.7 cm (1.3–2.2 in). Adult butterflies feed on nectar from flowers while larvae feed on a variety of plants including snowberry (Symphoricarpos), paintbrush (Castilleja), Buddleja, Diplacus aurantiacus and Scrophularia californica.
Oxycorynini are a tribe of American belids, primitive weevils of the family Belidae. Like in other belids, their antennae are straight, not elbowed as in the true weevils (Curculionidae). In contrast to other Belidae, Oxycorynini larvae feed on flowers or several types of fruit.
Florida arrowroot was the commercial name of an edible starch extracted from Zamia integrifolia (coontie), a small cycad native to North America.
Lycaena dorcas is a species of butterfly in the family Lycaenidae, the gossamer-winged butterflies. Its common names include dorcas copper and cinquefoil copper. The species was first described by William Kirby in 1837. It is native to North America. The species L. dospassosi was once included in L. dorcas.
Aphrissa statira, the statira sulphur, is a species of Lepidoptera in the family Pieridae. The species is a medium-sized yellow butterfly, with females more pale than males. They are found from southern regions of Florida and Texas through southern Brazil and northern Argentina. The caterpillars feed on the leaves of several local host plants, while adults prefer to feed on the nectar of red or orange colored flowers. The species is most noted for their dramatic migrations in the tropical areas of the Americas. They have been the subject of many studies about how butterflies navigate and orient during migration.
Cycasin is a carcinogenic and neurotoxic glucoside found in cycads such as Cycas revoluta and Zamia pumila. Symptoms of poisoning include vomiting, diarrhea, weakness, seizures, and hepatotoxicity. In metabolic conditions, cycasin is hydrolyzed into glucose and methylazoxymethanol (MAM), the latter of which dissociates into formaldehyde and diazomethane.
Zamia integrifolia, also known as coontie palm, is a small, tough, woody cycad native to the southeastern United States, and the Bahamas.
