Leaf-mine: A long white mine. Pupation external (Spencer, 1972: 62 (fig. 209), 65, as lonicerae).

Strongly widening, upper-surface, unbranched corridor; its first section usually follows the leaf margin for some distance. Pupation outside the mine; exit slit in upper epidermis (Bladmineerders van Europa).

Leaf mine is formed in the young tender leaf. Larva forming long white mine which widens (British leafminers).

Larva: Posterior spiracles with a distinctive horn-like process within the ellipse of bulbs (Spencer, 1972: 65, as lonicerae). The larvae are described Griffiths (1973), Dempewolf (2001: 166) and illustrated in Bladmineerders van Europa.

Puparium: Posterior spiracles with a distinctive horn-like process within the ellipse of bulbs (Spencer, 1972: 65, as lonicerae). The puparium is illustrated in Bladmineerders van Europa.
