The Two-barred Flasher (Telegonus fulgerator, formerly Astraptes fulgerator) is a large, distinctive skipper butterfly known for its iridescent blue body and quick, darting flight. The upperside is deep brown to black wings with iridescent blue at the base and on the thorax. The forewings feature a prominent off-white or light blue discal band and small white spots near the apex. The species complex is found across the Americas, ranging from southern Texas through Central America to northern Argentina. Adults often rest upside down under large leaves and feed on flower nectar or bird droppings.

Diet

  • The larval food plants include a wide variety of woody and herbaceous plants.

  • Adults visit flowers for nectar.

Range

  • Telegonus fulgerator is a widely distributed Neotropical species occurring from Mexico and Central America through much of South America.

  • It occurs in Mexico, including the Pacific lowlands, and is present in the Zihua region.

Habitat

  • It inhabits tropical dry forest, tropical rainforest, woodland, forest edges, clearings and secondary vegetation.

  • In the Zihua region, suitable habitat includes tropical dry forest, thorn scrub and other lowland vegetation along the Pacific coast.

  • Adults are often encountered in sunny openings and along forest edges, where they perch on foliage and make rapid, darting flights.

  • The species can occur across a broad range of elevations and habitat types, provided suitable host plants are present.

Description

  • A medium-sized skipper with a predominantly black upper surface and conspicuous blue to blue-green scaling around the basal portions of the wings.

  • The forewings have two prominent pale bands or groups of translucent spots, giving the species its common name, Two-barred Flasher.

  • The pale markings range from whitish to pale blue, while the underside of the wings is typically yellowish to orange.

  • The thorax is covered with bluish hairs, providing an additional feature useful for identification.

  • Caterpillars are highly variable in colour and pattern, but mature larvae commonly have a dark body with contrasting yellow markings along the sides.
