Subspecies include the nominate S. m. mazans, S. m. ascaphalus, S. m. hayhurstii, and S. m. tierra.

Appearance
A small with scalloped wing margins characteristic of the Staphylus. As a spread-wing skipper, it typically rests with wings held partially open rather than folded vertically. Detailed wing pattern descriptions are not available in the provided sources.
Habitat
Occurs in varied environments including riparian corridors adjacent to waterways, sandy or dune-like areas, abandoned roads, and gardens with diverse flowering plants. One documented observation occurred in a sandhill near Willow Creek in Colorado.
Distribution
Present in Middle America (Central America) and North America. Specific countries and states documented include: Mexico, United States (Arizona, Colorado, New Mexico, Texas, Oklahoma, Kansas, Missouri). The S. m. hayhurstii has been recorded in Colorado.
Seasonality
Activity period varies by geographic location and . Multiple per year occur in southern portions of the range. Specific periods are not well-documented in available sources.
Life Cycle
Complete with , larva, pupa, and stages. Caterpillars feed on grasses (Poaceae), though specific grass for S. mazans are not documented in the provided sources.
Behavior
Males perch in low areas such as wash bottoms, road depressions, and trails early in the morning, retiring to shaded locations during afternoon hours. This perching is characteristic of the and related roadside-skippers.
Ecological Role
function as when visiting flowers for nectar. Larvae serve as herbivores on grasses. The contributes to local biodiversity in riparian and grassland .
Human Relevance
Documented by citizen scientists and enthusiasts. Records contribute to regional biodiversity databases such as Butterflies and Moths of North America (BAMONA). Observations in Colorado represent range extensions and county records of interest to lepidopterists.
