in a leaf axil. From there ascends a narrow corridor with a thin
frass line. When the mine is 2-3 cm long the direction reverses.
The result is an elongate, whitish, lightly inflated blotch with
dispersed frass. Pupation external (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).
Described by Steuer (1980a). The larva is yellowish with a dark
brown head and a light brown prothoracic plate (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, although it may not be that sepcies and is more likely to be Elachista triatomea. The male
genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
