In autumn the larva makes a long, somewhat blistered, slightly transparent
corridor. In spring it mines the basal leaves that lie on the ground.
These mines are swollen, clouded green, opaque, and the mined tips
of the leaves are puckered and shrunken, filled with frass (Bladmineerders van Europa).
Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).
Rather thick, light yellow; head light brown. See Steuer (1973a)
for an illustration of the characteristic sclerites in the pronotum,
prosternum, and anal shield (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
See Patocka (1999a) and Patocka and Turcani (2005a) (Bladmineerders van Europa).
The adult is not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera
Dissection Group (check for update).
