Leaf-mine: A silvery sinuous gallery on the upper side, leading to a large,
papery blotch. Sometimes several galleries lead to the same blotch
(British
leafminers).
The
mine begins as a rather tortuous upper surface, epidermal, corridor.
As a rule several mines on a leaf, and when the corridors widen
they coalcesce into one white epidermal blotch. After a moult the
larvae start feeding from the palissade parenchyma that forms the
floor of their communal mine, which is not widened any more. Pupation
outside the mine (Bladmineerders
van Europa).
Larva:
The larva is illustrated in Bladmineerders
van Europa.
Pupa:
The pupa is in a silken cocoon amongst detritus; occasionally inside mine (British
leafminers).
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.
