Amauromyza chamaebalani (Hering, 1960)
Lathyrus tuberosus, Maastricht, Pietersberg
same, rather old, vacated, mine lighted from behind
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.
Fabaceae, narrowly monophagous (>)
Without further details Papp & Černý also mention Pisum; this needs further confirmation.
Larvae in June, July (Hering, 1957a).
BE not recorded (Fauna Europaea, 2008).
NE recorded (Ellis: Pietersberg, Poppelmonde valley).
LUX not recorded (Fauna Europaea, 2008).
