Eudaminae
Eudaminae is a subfamily of butterflies within the family Hesperiidae, commonly known as skippers. They are sometimes referred to as the "flat skippers" or "darters," although these terms are not universally applied and can be used for other skipper groups.
Characteristics:
Eudaminae butterflies are generally characterized by their robust bodies, hooked antennae, and rapid, darting flight. They often possess cryptic coloration, typically brown or gray, which aids in camouflage. Many species exhibit elongated tails on their hindwings, though this is not a defining characteristic of the entire subfamily.
Distribution:
The Eudaminae are primarily found in the Neotropical region (Central and South America), with some species extending into North America.
Life Cycle and Host Plants:
Like other butterflies, Eudaminae undergo complete metamorphosis (egg, larva, pupa, adult). The larvae (caterpillars) typically feed on plants from various families, including legumes (Fabaceae). Specific host plant preferences vary considerably between species.
Taxonomy:
The classification of skippers and their subfamilies has undergone revisions, and the precise composition and relationships within Eudaminae may be subject to change as further research is conducted. Genera typically included in Eudaminae include (but are not limited to): Astraptes, Epargyreus, Urbanus, and Codatractus. The exact number of genera and species within the subfamily is not static.
Significance:
Eudaminae butterflies play a role in pollination, although the extent of their contribution to ecosystem function compared to other pollinator groups is not fully quantified. Some species may be considered agricultural pests in certain regions due to their larval feeding habits.
