Lathyrus pratensis. The numerous small pale spots are caused by feeding punctures applied to the underside of the leaf.

mine
Long, whitish gallery, often partly along a thick vein, almost invariably beginning at the underside of the leaf, usually continuing largely or even entirely at the upper side; the first section of the gallery usually is conspicuously straight. Seen in transparency the criss-cross of the lower and upper side galleries forms a mottled pattern. Frass in alternating thread pieces. Pupation external.

notes
Mines also ib the wings of the stems and petioles; such mines may be up to 8 cm in length, and can hardly be distinguished from mines of Liriomyza strigata, that also may mine in the wings (Ostrauskas, Pakalniškis & Taluntytė, 2003a).
