A small (approx. 2 cm wingspan) moth with maroon and dark olive forewings and dark scarlet hindwings with a broad black marginal band. The scarlet and black hindwings will separate roseitincta from all other Alberta Schinia.

This little moth is unusual in that it is active night and day, as are also a few other Schinia species, such as the green Schinia meadi, and some species of Drasteria and Caenurgina. Chuck Harp (pers. comm. 2006) reports that roseitincta is associated with Tetraneuris acaulis (Pursch) Greene (aka stemless four-nerve-daisy, stemless hymenoxys, or rubberweed), the probable host plant . Like other Schinia species, it undoubtedly feeds on the flowering parts and seeds of the host plant, and is thus single brooded with a flight period closely linked to the chronology of the host. The Alberta specimen was collected on the night of June 2, 2006.

Schinia roseitincta occurs from southeastern Manitoba and the Black Hills of South Dakota west to southeastern Alberta, Montana, Colorado, Utah and New Mexico. The only Alberta record is a single fresh specimen collected by Ted Pike in the Red Deer River valley north of Jenner (east of Jenner Bridge).
