Cerodontha luzulae (Groschke, 1957a)
Luzula sylvatica, Bunderbos (leaf tip to the left)
Rather narrow corridor, upper-surface or interparenchymatous, 12-20 cm in length, about 2 mm wide. Mines yellow, contrasting against the dark green leaves, but sometimes they are deep purple (Blad, 1993a). The corridor changes direction at least twice. Generally it does not leave the blade. Frass in one or two large lumps. Pupation inside the mine.
Juncaceae, narrowly monophagous
Nowakowski (1973a) mentions August-October as the period that larvae occur, but larvae were found in the Netherlands in November, and Robert Chelt found in Britain a puparium in late January.
