The Least skipper is among the smallest skippers in North America, with a dark blackish brown forewing sometimes showing an orange patch and an orange hindwing broadly bordered in dark brown. It rests with forewings held up in a V and hindwings spread flat.

Caterpillars feed on grasses such as rice cutgrass and bluegrass in wet meadows, marshes and roadside ditches, while adults sip nectar from nearby low flowers. Flight is characteristically weak and low, with two to three broods produced through the warmer months.
