Distribution:

The species is found in most of Europe, except Iceland, Norway, Finland, Portugal and most of the Baltic region (Nieukerken 2016). Vertically, records are available from near sea-level to apr. 1200 m, with single specimens as high as 1600 m a.s.l. (Kurz & Kurz 2016).

Biology:

The species prefers mixed woods, wood edges and associated tall herb vegetation with young trees of the larval foodplant (Kurz & Kurz 2016). Adults are on wing from April to May and again from July to August. There are two generations per year (Nieukerken 2016). Larvae can be found almost continuously from June till October (Kurz & Kurz 2016). The foodplants, on which the larvae feed, are often infested also by other larvae of St. hemargyrella, larvae of Stigmella tityrella (Stainton, 1854), Parornix fagivora (Frey, 1861), Phyllonorycter maestingella (Müller, 1764), Mikiola fagi (Hartig, 1839) or Rhynchaenus fagi (Linné, 1758).

Larva. The larvae feed on on the leaves of Fagus sylvatica and Fagus orientalis (Nieukerken 2016).

Mine. "The mine consists of a rather wide corridor that often crosses a vein, and mostly runs from somewhere near the leaf margin in the direction of the midrib. The first part of the mine is relatively narrow, with a narrow central frass line. The following section is wider. In the final section the frass lies somewhat more irregular and concentrated in a narrow central zone" (Nieukerken 2016).
