scientific name    Tarachidia tortricina    

Dry wooded areas, grasslands and badlands.

In Alberta adults have been collected from late May to mid August.

A very small (1.8-2.1 cm) narrow-winged dull grey, olive or yellow moth with few markings. The head, thorax and forewings are dull greenish grey to olive, immaculate in most Alberta specimens but with a small dark dot at the reniform and orbicular, and with a dark vertical mark indicating the lower part of a postmedian line in others. Fringe concolorous. Hindwings light to dark sooty brown with white fringes. Adults are variable in color, from dull yellow with fairly distinct mrkings to grey without any markings. One of the smallest noctuid moths, easily overlooked or mistaken for a species of microlepidoptera.
