Elachista griseella (Duponchel, 1843)
Primary mines not known. Secondary mines are 35-45 mm long elongate blotches that usually descend from near the leaf tip, but sometimes are ascending. The mines never occupy the full width of the blade, but generally lie along the sides. Frass in a diffuse elongated stripe. Pupation external.
Elymus repens is the main host plant; the species occurs on other plants only in periods of high population density (Buszko, 1989a). The reference to Avena in Denmark by Sønderup (1949a) cannot be accepted, because the species does not occur so far to the north.
Timing of early larval stages unknown; hibernation as intermediate larva. The larva resumes feeding in early April, and vacates the mine for pupation around the end of April (Buszko, 1989).
