Morley’s Final Catalogue: The larvae of this extremely profuse kind feed on the leaves of Holcus mollis. Ubiquitous in all pastures where Harker had found it at Hacheston. Blythbro and Bentley woods, Cransford, Weston and on the Gorleston palings; in Monks Soham paddock it flies in late April and the first half of May immediately before dusk in great numbers just over the grass-tops (Mly).
Recent Status: A common species but with few Suffolk records.
Life Style: A single brooded species flying from May to June. The larvae mine leaves of grasses, particularly Holcus mollis, Arrhenanthemum elatius, Schedonorus arundinaceus and Phleum bertolonii. The young larvae hibernate. They pupate in a slight cocoon away from the mine.
Identification: This is a readily identified white or ochreous white species with scattered reddish brown scales forming a characteristic pattern. More Info
