mine

Gradually widening corridor, running either upwards or down. All frass is deposited in the earliest part of the mine. Often 2-3 larvae in a mine; in grasses with broad leaves sometimes more than one mine in a leaf.

host plants

Cyperaceae, Poaceae, narrowly polyphagous

Avenella flexuosa; Brachypodium sylvaticum; Carex elata; Calamagrostis arundinacea; Deschampsia cespitosa; Drymochloa drymeja, sylvatica; Elymus caninus; Melica nutans, uniflora; Milium effusum; Phleum; Poa chaixii, remota; Schedonorus giganteus; Sesleria albicans, argentea, caerulea, sadlerana.

phenology

Two generations; the larva of the first generation hibernates in the mine and makes a new mine in early spring. Larvae from October till end-May, and mid-June – end-July (Bland, 1996a; Traugott-Olsen & Nielsen, 1977a). However, although the species is very common in southern Germany, Steuer (1976a) did not succeed in finding occupied mines of the second generation.
