Oecophorini

Oecophorini moths are distinguished from other oecophorid tribes primarily by genitalic characters and wing venation patterns, requiring microscopic examination for definitive assignment. Externally, they resemble other Oecophorinae but often show more pronounced wing patterning with distinct fasciae or streaking. Separation from the related tribe Decadarchini and other oecophorine tribes is not reliably possible from photographs alone.

Adults are small to medium moths with wingspans generally ranging from 10–25 mm. Forewings are typically narrow to moderately broad, often with mottled, streaked, or spotted patterns in shades of brown, grey, ochre, or white. Hindwings are usually paler and more uniform. At rest, wings are held tent-like or slightly flattened over the body. Antennae are filiform and often as long as or longer than the forewing. Labial palps are usually prominent and curved upward.

Found in diverse terrestrial habitats including forests, woodlands, scrublands, and urban gardens. Larvae develop in concealed microhabitats such as leaf litter, dead wood, bark crevices, and silk-lined tunnels or cases. Adults are often encountered at light or resting on vegetation.

Widespread across temperate and tropical regions. Strongly represented in the Australasian region, with significant diversity also in the Palearctic, Nearctic, and Afrotropical regions. Exact boundaries are complicated by ongoing taxonomic revision of the subfamily.

Adult activity varies by species and region; in temperate zones, most species fly from spring through autumn. Tropical species may be active year-round. Many species show peak activity in late spring and early summer.

Complete metamorphosis. Larvae are concealed feeders, often constructing silk-lined tunnels, portable cases, or feeding within plant material, leaf litter, or detritus. Pupation occurs within the larval shelter. Specific details vary considerably among constituent genera and species.

Adults are primarily nocturnal and strongly attracted to artificial light. Larvae are cryptic and sedentary, feeding in concealed locations. Many species exhibit characteristic 'concealer' behavior, with larvae using silk to bind feeding material or construct protective shelters.

Larvae function as detritivores and decomposers, contributing to nutrient cycling in forest ecosystems. Some species feed on dead plant material, fungi, or decaying wood. They serve as prey for various insectivores including birds, bats, and spiders.

Generally of minor economic importance. A few species are minor pests of stored products or dried plant material. The group is of interest to lepidopterists and contributes to biodiversity surveys. Some species have been used as indicators of habitat quality in ecological studies.

• DecadarchiniAnother tribe within Oecophorinae; distinguished by genitalic and larval characters, with adults often similar in appearance
• AutostichinaeFormerly included in Oecophoridae; adults resemble Oecophorini but have different wing venation and genitalic structure
• DepressariinaeRelated subfamily of Oecophoridae; adults often broader-winged with different resting posture and larval habits
