Aroga trilineella is a moth of the family Gelechiidae. It is found in North America, where it has been recorded from Texas, Arizona, Colorado and California.[1] [2]
The wingspan is about 19 mm. The forewings are pale grey irregularly mixed brownish with scattered dark grey specks, a broad fuscous suffusion occupying the median longitudinal third from the base and whole apical area, which is preceded by an undefined transverse shade of light ground colour. There is a black streak along the fold from near the base to beyond one-third, and one in the disc from above the apex of this to the end of the cell. The hindwings are grey, lighter in the disc anteriorly.[3]
