Food Plant: Luzula sylvatica (Great wood-rush)

Mine: September - June

Notes: The mine formed is long, inflated and puckers the leaf surface. The larva often swaps leaves.Occurs in South West England, from Monmouthshire in Wales and the East of Scotland. Mines found on Luzula pilosa will probably be E.tengstromi. Larvae initially feed in a thin, straight, brownish gallery between the veins. This begins to broaden, with blacker frass, as shown here on L. sylvatica, before later forming a phyllonorycter-like blotch.

Data: Mine collected 27.xii.2022, Clatworthy Reservoir, South Somerset, VC5
