Recent Status: Widely recorded in Suffolk.
Life Style: A single brooded species that flies from May till August and comes to light. The larvae feed from spun leaves on a variety of herbaceous and woody plant and tree leaves. Betula is favoured
Identification: The moth is similar to some forms of Celypha lacunana. O. undulana shows more discrete markings. It lacks the incision on the basal edge of the central band and the central lacuna. The distal edge of the central band may have a double projection or a single broad one when these are merged. It may also resemble C. cespitana and C. rivulana but has no strong markings in the distal third of the wing. More Info
