Leaf-mine: A gallery which leads to blotch (no slit in lower epidermis so the
frass accumulates in the blotch) (British
leafminers).
Oviposition
on the upperside of the leaf, next to a vein. The mine begins as
a narrow corridor with a broad frass line, running along a vein.
Generally the corridor runs along the midrib, or along a lateral
vein. In the latter case the direction usually is towards the midrib.
The corridor abruptly widens into a blotch, containing much frass,
laying against the midrib. Pupation external (Bladmineerders
van Europa).
The
mione is also illustrated in the Encyclopedia
of Life.
Larva:
Greenish or yellowish white, head and pronotal plate reddish-brown.
The head is dark brown (British
leafminers).
Translucent white with a dark brown head; no ventral plates. See Gustafsson and van Nieukerken (1990a) for a description (Bladmineerders
van Europa).
Pupa:
Details unknown.
Adult:
The adult is illustrated in UKMoths. The genitalia are not illustrated by the Lepidoptera
Dissection Group (check for update).
