Sclerocecis (Paperback)

High Quality Content by WIKIPEDIA articles! Sclerocecis is a genus of moth in the family Gelechiidae. The Gelechiidae (twirler moths or gelechiid moths), are a family of moths. They are the namesake family of the huge and little-studied superfamily Gelechioidea, and as typical for these, the Gelechiidae's relationships with and delimitation against their relatives have been subject to considerable dispute. These are generally very small moths with narrow, fringed wings. The larvae of most species feed internally on various parts of their host plants, sometimes causing galls. Douglas-fir (Pseudotsuga) is a host plant common to many species of the family, particularly of the genus Chionodes which is consequently more diverse in North America than usual for Gelechioidea.
