Food Plant: Luzula sylvatica (Greater Wood-rush), L.pilosa (Hairy Wood-rush)

Egg: laid on underside of leaf

Mine: September-May

Notes: In the autumn a long thin gallery is formed, which may change direction. After hibernation an elongated blotch is formed, which may obliterate the early mine. The larva exits the mine to pupate. Found in shady deciduous woodland and gorges. Two mature larvae in mines on the same leaf of Luzula sylvatica.
