Leaf-mine: A gallery completely without coiled frass (British leafminers).

Ovipisition at the underside of the leaf, in the axil of a vein. From there a corridor, that does not widen much, zigzags between two lateral veins in the direction of the leaf margin. Frass at first in a narrow central line. Later the frass becomes widely dispersed; it never lies in coils (Bladmineerders van Europa).

Larva: The larva is yellow, dark head and prothoracic plate (British leafminers). The larva is also illustrated in Bladmineerders van Europa.

Pupa: Details unknown.

Adult: The adult is illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.

Hosts elsewhere:

Time of year - larvae: June - July, end August - October (British leafminers).

Time of year - adults: April and May, and again in July and August (UKMoths).
