larva in opened mine; upper surface of the mine
mine
Lower surface tentiform mine that occupies an entire leaflet; lower epidermis strongly folded. Fully developed mines are strongly inflated and the leaflet is so completely folded over the mine that the latter becomes practically invisible. In this stage the larva has consumed also all tissue in the roof of the mine, making the mine thereby very conspicuous. The pupa in a cocoon that consists of a loose lining of the walls of the mine.
hostplants
Fabacea, oligophagous
Lathyrus vernus; Lotus; Medicago; Trifolium alpestre, medium, pratense, repens, rubens; Vicia dumetorum, sativa, sepium.
Preference for Vicia sepium (Hering, 1957a).
phenology
Larvae in July and August – September (Emmet, Watkinson & Wilson, 1985a). However, in the UK final instar larvae have also been found in the months of November, December, and January (Bond, 2000a; Henwood, 1999a).

NE not recorded (Fauna Europaea, 2009).
LUX not recorded (Fauna Europaea, 2009).
distribution within Europe
Europe, except the Balkan Peninsula (Fauna Europaea, 2009).
pupa
Cremaster with two pairs of spines. The inner pair has shifted so far sidewards that the inner and outer pairs seem to form one whole. The inner spines are fairly slender, the outer ones are stout, and the two combined look like one long spine with a broad base (Gregor & Patočka, 2001a; Patočka & Turčáni, 2005a).
