Grass skippers

 ( Hesperiinae ) 

They are usually orange, rust, or brown in colour and have pointed forewings. Many species have dark markings or black stigmas on their forewings. Most members of this subfamily have an oval antenna club with an on the tip, although Carterocephalus and Piruna do not. The antennae generally has a sharp bend.

Hesperiinae larvae feed on many different types of grasses and Cyperaceae and palms, though some species are limited.

Adults typically visit flowers and hold their wings together while feeding. Hesperiinae are unique in that they hold their wings partially open while resting, with the forewings and hindwings held at different angles. This is known as the "jet-plane position". Most male grass skippers perch to await females.

Adults are strong fliers; they move quickly and usually in a linear direction. Some of the species, however, do flutter and these species patrol for females rather than perch.
