The only checkered skipper in Missouri: The white and black checkered pattern makes this a simple identification. Males tend to have larger white spots than females and have bluish hairs near the body, but the patterns are virtually identical. The lower side has a white and brown checkered pattern.
As a spread-winged skipper, this species most often rests with all four of the wings held out flat to the side.
Larvae are green, enlarged in the middle, tapering toward the end, covered with white hairs. Head and first segment of thorax brownish-black.
