About Dichomeris simpliciella (Busck, 1904)
Dichomeris simpliciella is a species of moth in the Gelechiidae family. It was first described by August Busck in 1904. This moth is found in North America. Within North America, it has been recorded from southern Alberta to Texas, eastern Washington, south-eastern Nevada, and Arizona, and it is also present in northern Mexico. The wingspan of Dichomeris simpliciella measures approximately 18 mm. Its forewings are split into two nearly equal longitudinal sections: the costal (leading edge) section is light ocherous, and the slightly larger dorsal (lower edge) section is dark fuscous. The dividing line between these two sections is sharp and almost straight, running from the base of the wing to the apex. The dark fuscous section is lightly overlaid with ochreous across its apical third, though the dark colour remains rather prominent along the termen just before the cilia. A distinct very light ochreous round dot sits at the end of the wing cell. Adult moths can be seen in flight from April to June, and there is a second flight period from August to November.
