Morley’s Final Catalogue: Not listed in the final catalogue but later recorded by Claude Morley.

Recent Status: A rare species in Suffolk with recent records of the mine and the imago.

Life Style: A single brooded species flying in May and June. The larvae mine in Brachypodium sylvaticum, Dactylis and Holcus. They hibernate fully fed in the mine before leaving it to pupate on a stem or leaf, supported by a silken girdle.

Identification: The moth is dark fuscous with a deep cream fascia at one half that is broader on the dorsum. It narrows to a greater extent in the male. The cilia are completely dark, a factor that separates it from other unifasciate Elachista species.
The larvae mine downwards in a leaf leaving a silken tube filled with frass behind them. There may be more than one larva per leaf. They are olive green with a brown head and appear dark in the mine. More Info
