mine

Initially an intestine-like wound, very narrow gallery; this abruptly widens into a large blotch; often the blotch is followed by a short and broad final corridor. Mine entirely upper-surface. Frass in the initial corridor in grains, mostly in two rows. Frsass in the blotch as coarse, dispersed grains. Pupation external, exit slit in upper epidermis.

Malva neglecta.

notes

Hering found the mines, and illustrated it, but the breeding failed. Only after Spencer was more successful the mines could be associated with a species that was already known, as adult.
