Choreutoidea

36. Choreutidae – metalmark moths

Small (10–15 mm wingspan) moths with a scaled proboscis and broad wings, often marked with patches of metallic scales. The adults are diurnal; they run and fly with rapid, jerky movements, and hold the wings elevated above the body when at rest. Larvae of most species are leaftiers, usually of monocots. Some larvae live within stems but are not true borers.

Until recently, the family Choreutidae was associated with the Glyphipterigidae or the Sesiidae , but it is now placed in its own superfamily. Approximately 400 species of choreutids are known worldwide. The family is most diverse in tropical regions. Thirtytwo species are known from North America, and nine of these are reported in AB. The family is in need of revision in North America. Heppner (1982, 1991a, 1991b) has revised some tropical groups and has put new manuscript names on specimens in the CNC, but the latter remain unpublished. Currently, specimens can only be identified by comparison with authoritatively determined material, although Dombroskie (2003) is helpful for several AB species.
