Large full depth blotch in the lower leaves; much frass in coarse
grains. The larva can make several mines. Pupation either in the
mine or in the ground. Mines cannot be distinguished from those
of Mompha lacteella (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).
Body brownish red; head black; prothoracic plate two dark brown
rectangular sclerites; anal plate light brown, thoracic feet dark
brown (Koster, 2002b; Koster and Sinev, 2003a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The adult is illustrated in UKMoths and the Encyclopedia
of Life. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera
