Cogia hippalus, commonly known as the Acacia Skipper, is a small, understated butterfly in the family Hesperiidae. It belongs to the group of pyramid skippers (genus Cogia), named for their angular, triangular wing shape and characteristic resting posture. This species is typically dark brown to gray-brown, with subtle pale or translucent spots on the forewings that may be faint or variable. The underside is usually lighter brown with delicate patterning, helping it blend into dry vegetation and bark. The Acacia Skipper is found in Mexico and Central America, especially in dry forests, scrublands, and open woodland habitats.

Diet

  • Adults feed on flower nectar and are often attracted to small flowers growing along washes, forest edges, and other sunny openings.

  • The caterpillar's host is promarily acacia plants

  • Adults may also obtain minerals from damp soil and moist streambeds.

Range

  • The Acacia Skipper has a broad Neotropical distribution extending from the southwestern United States through Mexico and Central America into northern South America.

  • Guerrero is within its range, including warmer Pacific-slope environments.

  • It is an occasional butterfly in the Zihua area, particularly around dry woodland, thorny vegetation, and stream corridors where suitable acacias occur.

Habitat

  • It favors dry tropical woodland, thorn scrub, open forest, grassland, canyons, washes, and forest edges.

  • In tropical areas it can occur in relatively dry seasonal habitats as well as along wetter drainage corridors.

  • Adults often remain close to the ground, flying in short, somewhat bouncing flights between shrubs and low vegetation.

Description

  • A medium-sized skipper with a wingspan of approximately 35–48 mm.

  • The upper surface is predominantly reddish brown to warm chocolate-brown.

  • The forewing has a conspicuous group of large translucent white spots, particularly toward the middle and outer portion of the wing.

  • The fringes are strongly contrasting: the forewing fringe is checkered, while the hindwing fringe is largely creamy white.

  • The underside of the hindwing is brown with a subtle lavender or purplish cast and irregular grayish bands.

  • Its combination of reddish-brown wings, prominent white forewing spots, pale hindwing fringe, and banded hindwing underside helps distinguish it from the similar Cogia calchas.
