Underwings are pale gray-brown with streaks of darker brown, sometimes reddish, and a wide golden-orange band along the edge. Upperwings are bright blue in males, pale blue-gray to brown in females. Adults are nectar feeders, often on members of the composite family. Larvae are found on Asters and relatives, also Verbena.

Diet

  • Caterpillars are unusually polyphagous and feed on plants in several families.

  • Larvae commonly feed on flower heads and developing reproductive structures rather than relying exclusively on leaves.

Range

  • Rekoa palegon ranges from Mexico south through Central America and the Caribbean to Argentina, with populations extending through much of northern and central South America.

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

  • It occurs in the Zihua area.

Habitat

  • It occurs in tropical and subtropical forest edges, scrub, woodland clearings and disturbed vegetation.

  • It is particularly associated with flowering plants and secondary growth, where its numerous larval host plants are available.

  • Adults can be encountered along roadsides, trails, gardens and open forest margins.

  • In the Zihua area, sunny tropical woodland and disturbed areas with flowering Asteraceae provide suitable habitat.

Description

  • A small hairstreak with a wingspan of approximately 23–28 mm.

  • The upper surface is generally dull brown, with relatively inconspicuous markings compared with the brilliant blue Rekoa marius.

  • The underside is grey to grey-brown with fine irregular lines and a distinctive orange-brown border along the outer margins.

  • The hindwing has a small tail and a contrasting orange eyespot near the anal angle.

  • The cryptic underside allows adults to disappear readily against dry leaves and vegetation.
