Leaf-mine: The
larvae initially mining the leaves in a short, contorted gallery.
As the larva develops it leaves the mine to feed externally, creating
windows on the upperside of the leaves (UKMoths).
Oviposition
at the leaf upperside, egg shell iridescent. Small, hook-like corridor,
mostly in a vein axil. Frass in a very thick central line. The larva
soon leaves the mine through an untidy hole and subsequenty feeds
living freely on the leaf (Bladmineerders
van Europa).
The
mine is also illustrated in British
leafminers.
Larva:
Mining larvae uniformly greenish yellow with a darker head and prothoracic
shield (Emmet, 1985a) (Bladmineerders
van Europa).
The
larva is illustrated in British
leafminers.
Pupa:
Pupation occurs in a ribbed white cocoon spun on debris. The
winter is passed in this stage. (UKMoths).
The cocoon is illustrated in British
leafminers.
Adult:
The adult is illustrated in UKMoths.
The male
and female
genitalia are illustrated by the Lepidoptera Dissection Group.
