Which butterfly family contains skippers such as the silver-spotted skipper?

The butterfly family containing skippers such as the silver-spotted skipper is Hesperiidae.

Hesperiidae is the skipper family, named for the rapid, darting flight of many species. Skippers generally have stout bodies, relatively large eyes, and antennae whose tips are often hooked rather than simply clubbed.

Although skippers are butterflies, their appearance and behavior can make them seem moth-like. Their wings are commonly held at distinctive angles, and many species fly quickly between flowers or sunlit perches. The family includes grass skippers, skipperlings, and spread-wing skippers.

Hesperiidae is separate from Papilionidae, the swallowtail family, and from Nymphalidae, which includes many familiar brush-footed butterflies. Classification of skipper subgroups has changed as genetic studies have refined relationships.
