Distribution


Imago

Wingspan 15–19 mm. Most members of this genus should be examined for genitalia for proper identity.
The ground colour of the forewing is pale ochreous with a dark longitudinal streak from base to apex. Near the apex it has two to three pronounced black streaks pointing to the apex, even present in worn specimens.
The female has a more pure ground colour like females of other Bactra species, but the dorsal portion of the forewing is not or hardly darker than the costal half.
