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).
Mine irregularly linear, whitish green normally adjoining margin of leaf, when old brownish (British
leafminers).
Larva:
The larva is described by de Meijere (1926),
Allen (1957b) and illustrated in Bladmineerders
van Europa.
Puparium:
Shining black; posterior spiracles each with 24-28 bulbs of bulbs
or bulbs (Spencer, 1976:
461; British
leafminers).
