Elachista trapeziella Stainton, 1849
From autumn till early spring the larva makes a quite narrow corridor with a total length of 12-16 cm, essentially running parallel to the leaf venation; the corridor may change direction 2-3 times. Generally the corridor lies about halfway the length of the leaf. In March-April this gallery abruptly gives way to an elongate blotch, that generally obliterates the original gallery. The larva may leave its mine and restart elsewhere by making a lower-surface opening in a new leaf, not far from the leaf-tip. Pupation external.
Luzula luzuloides, pilosa, sylvatica.
