Elachista unifasciella (Haworth, 1828)
In autumn the larva makes a long, somewhat blistered, slightly transparant corridor. In spring it mines the basal leaves that lie on the ground. These mines are swollen, clouded green, opaque, and the mined tips of the leaves are puckered and shrunken,filled with frass (Traugott-Olsen & Nielsen, 1977a).(
Dactylis and to a lesser degree Brachypodium, are the most important species (Steuer, 1973a). Traugott-Olsen & Nielsen (1977a) consider records from Holcus unreliable, and do not even mention Milium.
