Leaf mine: Blotch, starting in the centre of the leaf. An ill-defined accumulation of frass in its first part. The blotch develops with little consideration of the major veins. Several mines may occur in a leaf, and coalesce into one large blister (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.

Larva: The larva has short feet and dark markings on the prosternum and two spots on the meso- and meta-sternum (British leafminers). The larva is also illustrated in (Bladmineerders van Europa).

Pupa: Outside the mine (British leafminers).

Adult: Details unknown.
