Ancyloxypha numitor, the least skipper, is a North American butterfly in the family Hesperiidae. They have a weak, Satyrinae-like flight. The least skipper's rounded wings and slender body are distinctive. Their checkered antennae have no hooks. Males lack stigmata. The upper sides of the forewings are dark brownish black sometimes having a patch of orange. The hindwing is orange with a broad dark brownish-black band surrounding the orange area completely. The underside of the wings is orange with the hindwing discal area being a little bit darker. The hindwing veins are whitish. Its wingspan ranges from 17 to 26 mm.
There are four similar species in the least skipper's range. They are the European skipper (Thymelicus lineola), the tropical least skipper (Ancyloxypha arene), the orange skipperling (Copaeodes aurantiaca), and the southern skipperling (Copaeodes minima).
The European skipper has more pointed wings than the least skipper, the antennae are short and not checkered, and the upper side of the wings is mostly orange or reddish orange with thin black wing margins. Males also have very thin, black stigmata near the costal forewing edge... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Least Skipper is recorded against all the insects logged in Everglades National Park (28 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
