Plant Parasites of Europe

leafminers, galls and fungi

Stenoptilia graphodactyla

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.

BENELUX

BE recorded (Phegea, 2011).

NE not recorded (Fauna Europaea, 2011).

LUX not recorded (Fauna Europaea, 2011).

distribution within Europe

From Germany and Poland to the Iberian Peninsula, Italy, and Bulgaria (Fauna Europaea, 2011).

larva

Older larvae pale green with a dark dorsal line and the other length lines whitish.
