Nemoria latirosaria (Pearsall, 1906). [7019]

Nemoria latirosaria, collection of National Museum of Natural History, Smithsonian. Specimen collected 21-June-1935, White Mtns, AZ by John Sperry.

An uncommon moth known from a limited geographic range from Utah to Arizona, Nemoria latirosaria is distinctive in the extensive pink markings on the costa and abdomen. In the male genitalic structures figured in Ferguson (1985) Nemoria latirosariaappears to be related to N arizonaria and N unitaria. It is interesting to note that spring forms of Nemoria arizonaria also can show some rose to red coloring on the costa, but never as extensive as the development of this coloration on specimens of N latirosaria. The larval stages of Nemoria latirosaria are undescribed. The adults appear to be univoltine with a single brood flying in June. They have been recorded from northern Arizona and several localities in Utah.
