Leaf-mine: Larva
forming a linear leaf-mine, considerably widening at end (Spencer,
1976: 94-95, fig. 133).
An
upper-surface corridor, initially very shallow, gradually widening
(often quite broad in the end), not associated with leaf margin
or veins; mature mine often with a characteristic brown colouration.
Frass in two rows. The gold-coloured larva leaves the mine before
pupation, through a semicircular exit slit in the upper epidermis
(Bladmineerders
van Europa).
An upper surface gallery, narrow at first but, widening considerably towards the end (British
leafminers).
Larva:
The larva is illustrated in Bladmineerders
van Europa.
Puparium:
Details unknown.
