A huge family with over 900 species in Europe alone (Parenti, 2001a). Quite a few species live in rolled leaves, wich has given the family its vernacular name. Only a few of them have mining larvae. They are not well adapted to the mining habit: the mines have no well-defined shape, and generally the larvae mine only during the first few instars, to become free-living later. Also most species are polyphagous. The larvae of several species live as borers, wich makes them play a role in the cecidological literature. Important sources about the larvae are Brown (1987a) and Swatschek (1958a). Larvae of Tortricidae have 4 pairs of abdominal prolegs.
