Elachista nobilella Zeller, 1839

Short and relatively broad, flat, whitish mine. Pupation outside the mine.

hostplants

grassy plants (Commelinids); narrowly polyphagous

Agrostis stolonifera; Arrhenatherum; Bromus; Carex; Dactylis; Deschampsia flexuosa; Festuca versicolor; Holcus lanatus; Luzula pilosa.

According to Steuer (1976a), who has studied the biology of this species, at least in southern Germany Deschampsia flexuosa is the most important, an possibly only, host plant. The miner was found only where this plant was growing in half shade, and forming dense tussocks.
