habitat
Native grassland.

July to early September.

identification
A medium to large crambid (21-32 mm wingspan). Antennae of males bipectinate (see drawing in Kearfott 1908). Forewing yellowish gray (clay color) with a narrow whitish line from base to end of cell, its outer half bounded above by a thicker dark brown line, this brown line faintly continues to terminal line below apex; with a brown oblique line running to apex; 3-5 small dark dots in terminal row. The male genitalia are illustrated in Landry (1995). Alberta material belongs to the subspecies coloradella Kft. Similar to T. fernaldella nortella, but the latter has the oblique line lighter, males have unipectinate antennae, and fernaldella tends to fly earlier.
