  • Adults feed on flower nectar and may also visit damp ground for moisture and minerals.

Range

  • Phocides belus ranges from Mexico through Central America to Costa Rica.

  • Its type localities are in Mexico, including areas in the north and east of the country.

  • Guerrero is within its range, and it occurs in the Zihua area. It has also been found in the Laguna Potosí area of Guerrero.

Habitat

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

  • It is also found along forest trails and in areas where its larval host trees occur.

  • In Guerrero it is associated with warm lowland and foothill environments, including the tropical dry forests of the Pacific coast.

Description

  • A medium-sized, robust skipper with a wingspan of approximately 50–60 mm.

  • The upper surface is predominantly dark brown to black, with a subtle bluish or powder-blue sheen across the wings.

  • The forewings have small translucent spots, while the hindwings are broadly rounded and lack long tails.
