Grass skippers

provided by wikipedia EN

Grass skippers or banded skippers[2] are butterflies of the subfamily Hesperiinae, part of the skipper family, Hesperiidae. The subfamily was established by Pierre André Latreille in 1809.[1]

Description and distribution

With over 2,000 described species, this is the largest skipper butterfly subfamily and occurs worldwide except in New Zealand.[3] About 50 percent of grass skippers live in the Neotropics.[4] 137 species are native to North America. Around 38 species are native to Australia.[5] Genera Ochlodes and Hesperia exist exclusively in the Holarctic.[6]

They are usually orange, rust, or brown in colour and have pointed forewings.[2] Many species have dark markings or black stigmas on their forewings.[2] Most members of this subfamily have an oval antenna club with an apiculus on the tip, although Carterocephalus and Piruna do not.[7] The antennae generally has a sharp bend.

Hesperiinae larvae feed on many different types of grasses and sedges and palms, though some species are limited.[7][8]

Adults typically visit flowers and hold their wings together while feeding.[2] 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".[9] Most male grass skippers perch to await females.[7]

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.[7]

Genera incertae sedis

These[10] grass skipper genera have not yet been assigned to tribes:

Conservation

The following grass skippers are considered at risk.[11]
