Leaf-mine: Large full depth blotch, covering the entire distal part of a pinnula. The mine begins near the top, where an elliptic egg shell is attached to the underside of the rachis. Larva solitary. The mine contains much frass (Bladmineerders van Europa).

An upperside blotch at the tip of a pinna lobe (British leafminers).

Larva: The larva is described by de Meijere (1911, as Hylemyia cinerosa) and illustrated in (Bladmineerders van Europa). The cephalopharyngeal skeleton with the upper process shorter than the lower. Mouth hook with only one tooth.

Puparium: Described by Stork (1936a), as Pycnoglossa cinerosa) (Bladmineerders van Europa).

Comments: Ackland in Chandler(1978) did not indicate whether his host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere'.
