Leaf-mine:
The mine is a whitish blotch with scattered blackish frass (UKMoths),
usually low on the plant (British
leafminers).
Oviposition
on the basal part of the midrib. The young larva makes a number
of short corridors radiating from this point, either in the same
leaf, or on different ones; they have a central frassline, but their
final sections are free of frass. Later an elongate blotch is make,
also beginning on the midrib (although not necessarily its basal
part). Pupation external (Bladmineerders
van Europa).
Larva:
Greyish green; head and prothoracic plate black (Koster, 2002b;
Koster & Sinev, 2003a) (Bladmineerders
van Europa).
Pupa:
In a white cocoon, which is attached to vegetation or leaf litter
(British
leafminers). See also Patocka & Turcáni (2005a) (Bladmineerders
van Europa).
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.
