Leaf-mine:
Narrow whitish mine, with frass in distinct black lumps. Pupation
internal (Spencer, 1976:
422).
Whitish,
upper-surface, descending corridor, about halfway up the blade.
Frass in distinct black grains that are lying further apart than
their diameter. Pupation in the mine (Bladmineerders van Europa).
Larva: Anterior spiracles with 18-20, posterior spiracles with 8 bulbs; both are fist-shaped. (The posterior spiracles isn't dagger-shaped, like in Ch. milii).
Puparium:
Pale yellowish with darker markings; posterior spiracles each with
4-6, rarely 10 bulbs (Spencer,
1976: 422).
The orange-brown puparium can easily be discriminated from that of Ch. nigra because the ventral surface has a broad dark length zone (Bladmineerders van Europa).
Comments:
The life-cycle is described by Andersen (1991).
