The West-Mexican Spurwing (systaspes funebris) is a small butterfly belonging to the skipper family, Hesperiidae, specifically within the subfamily of spread-wing skippers. Found primarily in the western and southern regions of Mexico, this species is characterized by its rapid, darting flight—a trait common among skippers—and its tendency to rest with its wings spread flat rather than folded.
