Lycas argentea, the Fantastic Ruby-eye, is a small grass skipper in the family Hesperiidae. This species is found in Mexico and Central America, inhabiting grassy areas, forest edges, and open habitats. Adults are often observed flying low over vegetation or perching on grasses, with the characteristic quick, darting movements of grass skippers.

Diet

  • Adults presumably obtain nectar from small flowers and other plant resources in their forest habitats.

Range

  • Lycas argentea has a broad Neotropical distribution extending from Mexico through Central America to Colombia, with additional populations farther south in South America.

  • In Mexico, it occurs in several regions, including Guerrero. It occurs in the Zihua area, where tropical woodland and forest-edge vegetation provide suitable habitat.

Habitat

  • The Fantastic Ruby-eye is associated with tropical and subtropical woodland, forest edges, clearings and secondary vegetation.

  • It tends to occur where there is a mixture of shade and open vegetation, rather than in completely exposed grassland.

  • Adults are relatively inconspicuous and can spend much of their time among low vegetation and foliage.

Description

  • Lycas argentea is a small skipper with a forewing length of approximately 21–23 mm, giving it a wingspan of roughly 42–46 mm.

  • The upper surface is predominantly brown, with several yellowish translucent spots on the forewing. The male lacks the conspicuous forewing stigma found in several related Lycas species.

  • The eye is red in living individuals, a striking feature that helps explain the common name Fantastic Ruby-eye.
