Amauromyza chamaebalani (Hering, 1960)

Lathyrus tuberosus, Maastricht, Pietersberg

same, rather old, vacated, mine lighted from behind
mine
Oviposition usually at the underside, somewhere in the centre of the leaflet. From the eggs runs a an extremely short lower-surface corridor, followed by a hardly longer upper-surface corridor. This suddenly widens into a large, shallow blotch, initially greenish, later whitish. Almost always the blotch has a large number of tiny full-depth spots, giving it a perforate appearance. Frass in rather small, greenish grains. Pupation outside the mine; exit slit in the upper epidermis, not at the margin, but somewhere centrally in the blotch.
