Bactra furfurana, the mottled marble,[2] is a moth of the family Tortricidae described by Adrian Hardy Haworth in 1811.

Its habitat is damp marshy regions with adults flying in June and July.

[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.

The larva is shining green; head black, with a whitish line; plate of 2 dark brown.
