Nordstromia humerata

Nordstromia humerata is a moth in the Drepanidae family. It was described by Warren in 1896.^[1] It is found in north-eastern India.^[2]

The wingspan is 22-25 mm for females. The forewings are fawn-colour, but the costal edge is yellowish from the base to the middle. The lines are ferruginous, starting from dark brown costal spots. The first at one-fourth, oblique outwards, angled on the subcostal, then straight and vertical or slightly oblique to the inner margin beyond one-third. The second line from the costa at the middle, runs outward along the subcostal vein for two-thirds of the distance to the apex, then sharply angulated, incurved opposite the cell and outcurved below it, reaching the inner margin straight at four-fifths. The submarginal line is strongly denticulate and blackish. The marginal area is dark grey, with some irregular black marks before the fringe, which is chestnut with a pale basal line. The apical one-third of the costa has a chestnut streak, the apex itself with one or two snow-white spots. The cell-spot is large, blackish, followed obliquely below it by four small white spots edged with black, and sometimes altogether black. The hindwings are fawn-colour, in the females with the costal area ochreous and in the males with an ochreous tint suffusing the wing and leaving only the inner and anal margins fawn-colour. There is a curved postmedian line, abbreviated in the males, reaching to the ochreous costal part in the females, which also has a short antemedian line on the inner margin which is wanting in males.^[3]
