Stenoptilia graphodactyla (Treitschke, 1833)

mine

In autumn a short mine that descends into the leaf base, upon which the larva feeds throughout the winter on the rhizome. Also the young larvae of the second generation should make “a small mine”. Gielis only writes that the larvae feed on the leaves and flowers, later on the fruits.

host plants

Gentianaceae, monophagous

Gentiana pneumonanthe.

phenology

Hering (1957a) writes of two generations, with living larvae in autumn and in June, but according to Gielis (1996a) moths fly only in July and August, which implies a single generation.
