Description

Ectoedemia coscoja is a moth of the Nepticulidae family. It is endemic to Spain (Catalunya, Aragon, Andalusia). The wingspan is 4.3-5.1 mm. Adults are on wing from June to July. There is probably one generation per year. The larvae feed on Quercus coccifera. They mine the leaves of their host plant. The mine consists of a sinuous or contorted, gradually widening gallery, often following a vein for some distance, filled with brown or black frass. Pupation takes place outside of the mine. - - - -
