Scaptomyza (Scaptomyza) graminum (Fallén, 1823) [Diptera: Drosophilidae] Drosophila graminum Fallén, 1823c. Geomyzides Sveciae : 8.

Leaf-mine: Corridor-blotch mine. Mine begins as a normally upper surface deep corridor and becomes a blotch lying centrally in the leaf, often touching the leaf petiole, if leaves are small larva may mine across the stem to another leaf. Pupation internal or external, sometimes in a separate pupation mine. Frass partly in grains or streaks but mainly in clumps towards margins of blotch. Larva: The larva is illustrated by Ellis (Nederlandse bladmineerders). Puparium: Details unknown. Hosts in Britain: Amaranthaceae       ?
