They are the namesake family of the huge and little-studied superfamily Gelechioidea, and 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.By the late 20th century, over 900 genera with altogether more than 4,500 species were placed here, with about 650 known from North America alone. While these figures are certainly outdated due to the many of reevaluations of Gelechioidea and new descriptions of twirler moths, they still serve to give an impression of the enormous biodiversity contained in this important family.Being abundant, fecund plant-eaters, many species are agricultural pests, including: Anacampsis sarcitella – pack moth Anarsia lineatella – peach twig borer Aproaerema modicella – groundnut leafminer Keiferia lycopersicella – tomato pinworm Pectinophora gossypiella – pink bollworm Phthorimaea operculella – potato tuber moth, tobacco splitworm Sitotroga cerealella – angoumois grain moth Tecia solanivora (Povolny, 1973) – Guatemalan potato moth, Central American potato tuber moth Tuta absoluta – tomato leafminer, South American tomato mothThe voracious habits of their larvae make twirler moths suitable for biological control of invasive plants. The spotted knapweed seedhead moth (Metzneria paucipunctella), for example, is used to control spotted knapweed (Centaurea maculosa) in North America. Even more subtle plant-host interactions have been discovered in these moths. The Guatemalan potato moth may become a harmful pest. If it is not entirely eradicated from a potato field, but allowed to infest some plants (up to around 20% in one study), the overall harvest will increase, and include an increased number of extremely large tubers."@en }
