Aphrissa statira

[9][10] Female statira sulphur are lighter yellow to greenish-white with black borders at the apex and outer margin.

[4][6] The species ranges from Argentina north through Central America, extending as far as southern Texas and Florida and are also found on nearby islands.

[9] In Florida, the caterpillar live and feed on coinvine (Dalbergia ecastophyllum) and Powder-puff (Calliandra), both members of the pea family (Fabaceae).

[6] When feeding on the nectar of red flowers, statira sulphur serve as important pollinators.

[12] Male statira sulphur are often found in large groups which can be as dense as 100 butterflies within a square foot.

[7] Female statira sulphur lay their eggs singly on the small, young leaves of host plants.

[6] Statira sulphur are notable for their large annual migrations in the tropical areas of the Americas between May and July.

[7] There are many accounts on the impressiveness of statira sulphur migration, when the butterflies can be seen flying in very large groups.

To facilitate migration, statira sulphur have evolved several mechanisms to ensure they fly to the correct destination.

[10] Much research has been done on the statira sulphur for its ability to adjust its direction of migration under windy conditions.

When experimentally exposed to a reversed magnetic field, the butterflies tended to orient themselves for migration in the opposite direction as they normally would.

[10] This is consistent with several species of migratory birds which also use the Earth's magnetic field to differentiate the direction of the equator and the poles.

[10] Additionally, in their migration, statira sulphur are also influenced by the direction of the Sun and by the presence of landmarks.

Statira sulphur demonstrate a preference for red flowering plants.
Statira sulphur form into groups, here with the straight-line sulphur ( Rhabdodryas trite ) and the apricot sulphur ( Phoebis argante ), along the Cristalino River in the Southern Amazon region of Brazil.
