-Gilbert's Flasher  (Telegonus alector)


Gilbert's Flasher (Telegonus alector), is a striking neotropical skipper butterfly found from Mexico through Central America. This medium-sized butterfly typically has a wingspan of approximately 2 to 2.5 inches and is distinguished by its dark, almost black wings that lack the white spots common in related species. One of its most captivating features is the iridescent blue sheen that covers the upperside of its body and the bases of its wings, providing a brilliant flash of colour when viewed in the right light. In their tropical forest habitats, these butterflies are known for their unique resting posture, where adults often roost upside down on the undersides of large leaves to hide from predators.

Diet

  • It belongs to the skipper subfamily Eudaminae, whose caterpillars are generally associated with broad-leaved woody plants, particularly members of the legume family.

  • Adults visit flowers for nectar.

Range

  • Telegonus alector is a Neotropical species occurring primarily in northern and western South America.

  • Its range includes Colombia and Ecuador, with the species centred largely in the northwestern part of South America.

  • Recent taxonomic studies recognise several closely related Telegonus species within what was previously considered a more broadly distributed species complex.

Habitat

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

  • Adults are associated with sunny openings and forest margins where suitable flowering plants and larval host plants occur.

  • They may be encountered perching on foliage, shrubs and low branches before making rapid flights through the surrounding vegetation.

Description

  • A medium-sized, dark brown skipper with the compact, robust appearance typical of the genus Telegonus.

  • The wings are predominantly dark brown to blackish brown, with contrasting pale, translucent spots forming a broken band across the forewings.

  • The hindwings are generally darker and less prominently marked, with rounded margins and no long tails.

  • The combination of dark wings, pale forewing markings and rapid flight is characteristic of Telegonus and helps distinguish it from many other tropical skippers.
