Autochton potrillo, commonly known as the Potrillo Skipper, is a fast-flying butterfly in the family Hesperiidae. The wings are generally dark brown to black, marked with small pale or translucent spots, though these markings can be subtle and variable. Compared to species like the Broad-banded Skipper, A. potrillo lacks a bold continuous band, instead showing a more broken or reduced spotting pattern. The underside is typically lighter brown with faint markings, providing camouflage when the butterfly rests. This species is found in Mexico and Central America, inhabiting tropical forests, clearings, and edges. Adults often perch on leaves or low vegetation, returning repeatedly to favored spots, and may visit flowers or feed on moisture from soil and organic matter.
