Mines of Agromyza vicifoliae on Vicia Image: Rob Edmunds (British leafminers)

Leaf-mine: Mine initially linear, adjoining margin of leaf, later developing into a blotch, always on the mid-rib (Spencer, 1976: 145, fig. 265).

Blotch, preceded by a corridor that closely follows the leaf margin. The blotch is mined much deeper (and therefore more transparent) than the corridor. The blotch is precisely positioned over te midrib of the leaflet. Frass very sparingly in the corridor, in the blotch as a few large lumps. Pupation outside the mine (Bladmineerders van Europa).

Forms a blotch over the mid-rib without an initial gallery mine. Frass dispersed (British leafminers).

Larva: Posterior spiracles each with 3 bulbs (Spencer, 1976: 145).

Puparium: Yellowish-red (Spencer, 1976: 145).

Distribution in Great Britain and Ireland: Widespread but local in Britain including Surrey (Box Hill), Dunbarton (Bonhill) (Spencer, 1972: 39), Warwickshire (Ansley) (Robbins, 1991: 46) and Cambridgeshire,
Glamorgan and South Essex (NBN Gateway - N.B. includes Watsonian Vice Counties having publicly available records that fall within or overlap the vice county border at 10km resolution or better i.e. a record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below).

Distribution elsewhere: Widespread throughout much of continental Europe, including Norway, Sweden and Sicily (Spencer, 1976: 145), The Netherlands (Bladmineerders van Europa), Germany (Spencer, 1976: 550), Belarus, Corsica, Czech Republic, Estonia, French mainland, Latvia, Lithuania, Poland, Romania, Slovakia, Spanish mainland and Switzerland (Martinez in Fauna Europaea).
