Satyrini

Boisduval, 1833

Alpines, Arctics, Nymphs, Satyrs, Graylings, Ringlets

Satyrini is the largest tribe in the Satyrinae, containing approximately 2,200 of . The group includes well-known butterflies such as graylings, ringlets, and . Recent molecular phylogenetic studies have substantially revised the tribe's , incorporating many formerly placed in the tribe Elymniini. The tribe's evolutionary is closely tied to the diversification of grasses.

Habitat

vary widely among subtribes. The subtribe Pronophilina is restricted to Andean cloud forests from Venezuela to Bolivia. The infratribe Neosatyriti occurs in puna, pampas and subantarctic grasslands, Valdivian forests, and Chilean matorral from sea level to nearly 5,000 m elevation. In southern Brazil, Satyrini are distributed across multiple phytoecological regions including grassland, forest, and ecotonal areas.

Distribution

Worldwide distribution with distinct patterns among subtribes. Some subtribes are restricted to single biogeographic regions: Pronophilina to the Andes, Neosatyriti to southern South America from Patagonia to northern Peru and along the Atlantic coast. Documented in Rio Grande do Sul State, southern Brazil; southeastern United States; Peru (Amazonian region and Eastern Andean slopes); and southeastern Peru (Madre de Dios department).

Diet

Larval of many are grasses (Poaceae). The tribe's diversification is considered closely related to the evolution of grasses. Uncommon feeding preferences occur in three : Euptychia, Ragadia, and Acrophtalmia feed on Lycopsida (clubmosses), with some Euptychia species reported to feed on mosses of Neckeraceae. Multiple euptychiine species feed on herbaceous bamboos (Poaceae: Bambusoideae: Olyreae) including Taquara micrantha and Olyra latifolia. Magneuptychia harpyia has been documented feeding on seedlings of Euterpe precatoria (Arecaceae).

Host Associations

Poaceae - larval Primary for many
Poaceae: Bambusoideae: Olyreae - larval Herbaceous bamboos including Taquara micrantha and Olyra latifolia
Lycopsida - larval Uncommon for Euptychia, Ragadia, and Acrophtalmia
Neckeraceae - larval Mosses reported for some Euptychia
Euterpe precatoria - larval Arecaceae palm; reported for Magneuptychia harpyia

Life Cycle

with , , , and stages. stages have been documented for multiple euptychiine , with supporting recent generic arrangements and revealing putative synapomorphic characters of larvae and pupae. capsule morphology and other larval characters have taxonomic significance for distinguishing closely related species.
