Hitherto only known in Belgium from the specimen in 1938, which is also the oldest known specimen of this species.
Native
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.
Early stages are unknown. The adults fly at night and come to light.
The adults fly from mid-June towards late August.
Unknown.
It inhabits wet meadows and marshes where Carex and Juncus are abundant.
