Leaf-mine:
Mine
irregularly linear, whitish green normally adjoining margin of leaf,
when old brownish (Spencer, 1972: 89 (fig. 304), 92; Spencer,
1976: 461, 463 (fig. 808).
An
upper-surface, strongly widening corridor, often following the leaf
margin for some distance, with much blackish green, deliquescent
frass in its centre. Pupation outside the mine; exit slit in upper
epidermis (Bladmineerders van Europa).
The
mine is also described and illustrated in British
leafminers.
