Family Hesperiidae

The Hesperiidae are members of the Superfamily Hesperioidea. Worldwide in distribution, skippers are richest in the tropics. More than 3,500 species are described, with approximately 275 in North America, many of which are found only in Arizona and Texas. Most skippers are small to medium, usually orange, brown, black, white, or gray. A few have iridescent colors. Skippers have large eyes, short antennae (often with hooked clubs), stout bodies, and three pairs of walking legs . Their flight is often rapid, making wing movement appear blurred. Adults of most species have long probicscises and feed on floral nectar, but some also take up nutrients from bird droppings. Males have scent scales found in modified forewing patches. Males of most species locate mates by perching (grass and giant-skippers), though some patrol, especially in the open-winged skippers. Globular eggs are laid singly.
