The moth has a wingspan of 13–19 mm. Its habitat is damp marshy regions with adults flying in June and July. Adults are very similar to Bactra lancealana.[5] Meyrick describes it - Forewings slightly narrower than in Bactra lancealana, costa straighter; light ochreous or ochreous-brownish, indistinctly darker-strigulated; basal patch, central fascia, and an apical streak darker ochreous or brown, indistinct, sometimes nearly obsolete. Hindwings are grey. The larva is shining green; head black, with a whitish line; plate of 2 dark brown.[6] Julius von Kennel provides a full description.[7]

The larvae feed within the stems of various rushes, such as Schoenoplectus lacustris and Juncus conglomeratus, hollowing out the stem.
