several genera formerly included in Oecophoridae were transferred to family Elachistidae by Hodges in Kristensen (1999).
Explanation of Names
Larvae usually feed concealed in webs or in rolled or tied leaves of food plant
37 species in 20 genera in our area (1).
wingspan 3-30 mm (usually closer to 30 mm)
"The vast majority of oecophorids can be recognized by the shape of the male gnathos, which is fused to the tegumen without articulation" (2). This is a feature shared by Stathmopodidae. "However, there are exceptions, such as Deuterogonia [not present in NA], that lack the gnathos entirely" (2).
"Most oecophorids consume dead plants or fungi, but some feed on live plants, notably the most basally arising branch containing Pleurota and its allies" (2).
