Pseudolycaena damo is a Neotropical species of butterfly in the family Lycaenidae. Upper side: Vibrant, sky-blue wings in males, often with a slight metallic sheen. Females are slightly duller, with more subdued blue tones and additional brown markings near the edges. Underside: Light gray to silvery with faint brown or white markings that enhance its cryptic nature.

Diet

  • Caterpillars feed on a variety of woody plants.

  • Larvae feed on young shoots and foliage and may shelter among leaves.

  • Adults visit flowers for nectar and may also feed on fermenting fruit and plant juices.

Range

  • Pseudolycaena damo ranges from Mexico through Central America to Panama, with separate populations in western Ecuador and northwestern South America.

  • It occurs in both eastern and western Mexico, and Guerrero falls within its broad Mexican range.

  • It occurs in the Zihua area.

Habitat

  • It occurs in tropical dry forest, humid lowland forest, scrub, woodland edges and secondary vegetation.

  • In Mexico it occupies both seasonally dry and wetter tropical environments.

  • Adults are usually encountered around forest margins, clearings and flowering vegetation.

  • The western Mexican populations are particularly associated with warm lowland and foothill habitats.

Description

  • A relatively large hairstreak, with a wingspan of approximately 45–55 mm.

  • The upper surface is strikingly iridescent blue to sky-blue, with darker brown or blackish areas along the margins and wing bases.

  • The blue colour can appear brilliant turquoise or violet-blue depending on the angle of light.

  • The underside is brown to grey-brown with a distinctive arrangement of pale, separated spots and lines. This disjointed spotting is characteristic of Pseudolycaena and provides effective camouflage among leaves.

  • The hindwings have short tails and contrasting markings near the anal angle.
