Pterolonchidae
Pterolonchidae is a small family of minute moths in the superfamily Gelechioidea, comprising approximately 19 species across seven genera. The family has undergone substantial taxonomic revision, with genera reassigned from multiple other families based on cladistic analysis. Species are distributed across every continent except Australia and Antarctica, with notable concentrations in the Mediterranean region, western North America, and southern Africa. Several species have significant ecological and economic importance, including one used as a biological control agent for invasive knapweeds and another that is a major agricultural pest of cereal crops.
