Butterflies of Dominica


Banded Orange Heliconian,

Banded Orange Heliconian or Dryadula phaetusa, also known as the Banded Orange Heliconian is a species of butterfly native from Brazil to central Mexico, and in summer it can be found rarely as far north as central Kansas. Its wingspan ranges from 86 to 89 mm, and it is coloured a bright orange with thick black stripes in males, and a duller orange with fuzzier black stripes in females.
It feeds primarily on the nectar of flowers and bird droppings, and its caterpillar feeds on passion vines including Passiflora tetrastylis. It is generally found in lowland tropical fields and valleys. This species is somewhat unpalatable to birds and belongs to the "orange" Batesian mimicry complex.

Gulf Fritillary

The Gulf Fritillary or  Agraulis vanillae, is a striking, bright orange butterfly of the family Nymphalidae, subfamily Heliconiinae. These were formerly classified in a separate family, the Heliconiidae or longwing butterflies, and like other longwings this species does have long, rather narrow wings in comparison with other butterflies. It is not closely related to the true fritillaries. It is a medium to large butterfly, with a wingspan of 6–9.5 cm.Its underwings are buff, with large silvery spots.It takes its name from migrating flights of the butterflies sometimes seen over the Gulf of Mexico.

The Gulf Fritillary is commonly seen in parks and gardens, as well as in open country. Its range extends from Argentina through Central America, Mexico, and the Caribbean to the southern United States, as far north as the San Francisco Bay Area on the west coast. It is occasionally found farther north in the US.

Julia Longwing

Julia Longwing or Dryas iulia  commonly called the Julia Butterfly or Julia Heliconian, is a species of brush-footed butterfly. 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.The species is popular in butterfly houses because it is long-lived and active throughout the day.
Its wingspan ranges from 82 to 92 mm, and it is colored orange (brighter in male specimens) with black markings.This butterfly is a fast flier and frequents clearings, paths, and margins of forests and woodlands. It feeds on the nectar of flowers, such as lantanas (Lantana) and Shepherd's-needle (Scandix pecten-veneris). Its caterpillars feeds on leaves of passion vines including Passiflora affinis and Yellow Passionflower (P. lutea) in Texas.

Zebra Longwing

Zebra Longwing or Heliconius charithonia commonly known as  Zebra Heliconian, is a species of butterfly belonging to the subfamily Heliconiinae of the Nymphalidae. It was declared the official butterfly for the state of Florida in the United States in 1996.
The butterfly ranges over parts of North, Central and South America, as well as the Caribbean. In North America the butterfly is found in the southern parts of the United States . In South and Central America, it has been recorded in Mexico, Costa Rica, Panama, Colombia, Ecuador and Venezuela.
The caterpillar feeds on Yellow Passionflower (Passiflora lutea), Corky-stemmed Passionflower (Passiflora suberosa), and Two-flower Passionflower (Passiflora biflora). The adults are unusual among butterflies in that they eat pollen as well as sip nectar. This ability contributes to their longevity—3 months as an adult.
