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. The same mine on Luzula sylvatica photographed on three occasions, firstly after collection on 27.xii.2022, when it is just a thin, straight, brownish gallery between the veins. Then, on 08.i.2023, when the gallery has begun to widen, and the frass becomes blacker, and finally on 21.i.2023, when the larva has begun to produce the broad, phyllonorycter-like blotch that is characteristic of this species.

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