There are about 600 separate species of swallowtail butterflies.
Swallowtails live on every continent except Antarctica.
They typically feed on nectar from flowers and are important pollinators.
Swallowtail butterflies have large, colorful wings, patterned with black and yellow or black and white.
They have a distinctive tail on their hindwings, which gives them their name.

The body of a swallowtail butterfly is typically thin and elongated, and they have large, compound eyes.
The wingspan of a swallowtail butterfly can range from 5 - 15 centimeters (2 to 6 inches).
Swallowtails weigh between 0.04 - 0.3 grams (0.0014 - 0.0105 ounces).
Swallowtails are active during the day, flying and feeding on nectar from flowers.

Habitat and Distribution
P. antimachus live in the tropical rainforests of west and central Africa.
The distribution area (range) stretches from Angola, Cameroon, Democratic Republic of the Congo, Republic of the Congo, Gabon, Ghana, Ivory Coast, Liberia, Nigeria, Sierra Leone, and Uganda.
It is much rarer in the west of its range (Guinea to Cameroon) than in the eastern parts of its range.
It probably stays in forest canopy but males come down to mud-puddle.
Swallowtails are found everywhere in the world except for Antarctica.
A swallowtail butterfly’s habitat can vary depending on the species, but many species are found in wooded areas, gardens, and fields.
They are typically found near sources of nectar, such as flowers, as well as near their host plants, fennel, parsley, and dill, which are used for laying eggs.
Some species live near swamps, marshes, or rainforests.
Other species prefer mountainous or coastal areas.
Swallowtails are less common in arid or desert regions.
Males flutter close to the ground near rivers and streams while females spend their life high up in the forest canopy.
During the breeding season, the Giant African Swallowtail can be seen flying above the rainforest canopy in western and central Africa, and on grassy hilltops.

Diet and Behavior
The male is larger than the female and can be seen in groups at nectar.
The females show themselves less, continually flying high above the treetops.
It has been seen hill-topping in Liberia.
They are strong fliers that have a distinctive flutter flight pattern when they are looking for a place to rest.
Though swallowtails are typically solitary creatures, they will occasionally gather to puddle.
Puddling involves a group of swallowtails coming together in marshy, damp areas to acquire the nutrients that have leeched from the soil.
Though usually docile creatures, male swallowtails can become quite aggressive during mating season and when defending their territory.
Adult female swallowtails typically lay their eggs on the leaves of host plants, which include fennel, parsley, and dill.

Colorful swallowtail butterflies have a diverse diet, which includes a variety of different plants.
They feed on the nectar of a wide range of flowers, including thistles, clovers, and milkweeds.
Some species of swallowtail butterflies also feed on rotting fruit and tree sap.
Swallowtails have a preference for red, orange, and yellow flowers.
Researchers speculate that the giant butterfly most likely gets its toxin when its caterpillar ingests the leaves of Strophanthus gratus, a thick, woody liana that winds among the treetops and bears flagrant flowers.
The plant contains high concentration of the cardiac glycoside, ouabain, it is odorless but very bitter and extremely toxic.
Ouabain have long been used by Somali tribesmen and other groups to poison hunting arrows.
It is rumored that a sufficiently concentrated ouabain dart can bring down a Hippopotamus, probably as the result of respiratory or cardiac arrest.
Life Cycle
The lifecycle of a swallowtail butterfly typically includes four stages: egg, larva (caterpillar), pupa (chrysalis), and adult.
The female butterfly lays her eggs on the leaves of host plants.
The eggs hatch into larvae (caterpillars), which feed on the leaves or stems of host plants.
After several weeks of feeding and growing, the caterpillar enters the pupal stage, where it forms a chrysalis.
Swallowtail butterflies migrate seasonally.
Swallowtail butterflies, including species such as the Eastern Tiger Swallowtail and the Canadian Tiger Swallowtail, migrate seasonally.
