They are united on the basis of abdominal and pupal structures (Hodges 1999a). Approximately 1200 species of Elachistidaeare known worldwide; 309 species have been reported from North America, 56 of which are reported from AB.  24.1. Ethmiinae Small ( 20–30 mmwingspan) moths with long, broadly rounded wings, the forewings often strikingly marked with black spots on a white and/or gray background. Adults of many species are diurnal. At rest, they hold their wings closed and rolled tightly over the abdomen. Larvae of most species are external feeders on Boraginaceaeor Hydrophyllaceae. Most are host-specific at the genus level. The subfamily Ethmiinaecontains approximately 250 species worldwide, concentrated in the Neotropics and southwestern North America. Fifty-five species are known in North America; three of these are reported from AB. Th is group has been given family status in the past, but its position within the Elachistidaeis now widely accepted. They are a well known group in North America. Th ey were revised for the New World by Powell (1973), with two new species described since, from FL. 127 * R  Pyramidobela quinquecristata(Braun, 1921) Aug M– – T: Powell (1973)L: None C: UASM 128 * R  Ethmia monticola(Walsingham, 1880) Jun– Jul M – G T: Powell (1973)L: Bowman (1951), Powell (1973)C: CNC, NFRC, PMAE, UASM 129 * R  Ethmia albicostella(Beutenmüller, 1889) Jun– Jul M – g T: Powell (1973)L: Powell (1973)C: CNC, NFRC  24.2. Depressariinae Small ( 15–30 mmwingspan) moths with broad, rounded wings. Adults rest with the wings closed and held flat over the abdomen. Diapause is in the adult stage in most species; adults of most species fly very late in the fall and again early in the spring. Larvae are leaftiers, seed feeders, and stem borers in dicots. Approximately 600 species of Depressariinaeare known worldwide. Ninety-seven species are known from North America; 29 of these are reported from AB. The Depressariinaeare fairly well known in North America. Th e group was revised by Clarke (1941)and Hodges (1974). The latter added several new species but included few genitalia illustrations; both works are required to make reliable determinations. In both works, the Depressariinaewere considered a subfamily of the Oecophoridae. More recently, they were given the status of family, but Hodges (1999a) placed them within the Elachistidae, an arrangement we follow here. 130 R  Agonopterix gelidella(Busck, 1908) Jul– Aug M B – T: Hodges (1974)L: Bowman (1951), Prentice (1965),? Hodges (1974), Pohl et al.

(2004b)C: CNC, NFRC, UASM  24.3. Elachistinae– grass miner moths Minute ( 6–14 mmwingspan) moths with narrow lanceolate wings. Most species have white forewings with tiny black dots, or black wings boldly marked with white spots. The hindwings have straight sides, a sharp point, and a wide fringe on the trailing margin. Adults of most species are diurnal. Larvae of most species are miners in monocots. Approximately 250 species of Elachistinaeare known worldwide. Species richness is particularly notable in southern Europe and North America. One hundred species are known from North America, mostly in the genus  Elachista. Twenty-one species are known from AB; many more probably remain to be discovered in this poorly collected group. Th e North American species have been revised recently by Kaila (1995a, 1995b, 1996, 1997, 1999a, 1999b).
