-Cymaenes isus (Fawn-spotted Skipper)

Cymaenes isus, commonly known as the Fawn-spotted Skipper, is a small butterfly in the family Hesperiidae. It is a subtle species, recognized by its warm brown (fawn-colored) wings marked with small pale spots, especially on the forewings. The upper side is typically medium to dark brown with scattered light spots, while the underside is paler brown with softer, less distinct markings, providing effective camouflage when the butterfly rests. Like other skippers, it has a compact body, hooked antennae, and quick, darting flight.
