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 after collection on 27.xii.2022, and then three weeks later on 21.i.2023, showing how the larva begins feeding in a straight, brownish gallery between the veins, before broadening and forming a phyllonorycter-like blotch that distorts the leaf.

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