larva overwinters in a narrow crescent shaped mine on the the lower
leaf surface and then forms a large blotch mine next spring (British
autumn the mine begins as a brown, narrow and inconspicuous, lower-surface
corridor. The larva is capable of leaving its mine and restarting
elsewhere, possibly in another leaf. In April - May of the following
spring a full depth transparant blotch is made, from which most
frass is ejected. The mined leaf soon drops, which makes the mine
even more difficult to detect (Simpson, 2004a) (Bladmineerders van Europa).
The mine is also illustrated in UKMoths.
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).
Deep green; described by Bradley et al. (1979a) (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. The male
genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
