Celaenorrhinus fritzgaertneri (Fritzgaertner's flat), is a species of spread-wing skipper in the butterfly family Hesperiidae. Upper side: The forewings are dark brown with creamy white spots forming a distinctive pattern. The hindwings are dark brown, sometimes with faint lighter markings near the edges. Underside: Mottled with shades of brown, gray, and tan, providing effective camouflage against tree bark and foliage. The flat resting posture of its wings is characteristic, giving it the name "Flat."
