Leaf-miner: An irregular gallery filled with greenish frass, leading to a circular
or oval blotch with blackish frass arranged in a spiral fashion
very first part of the mine is a densely contorted corridor of about
2 mm long, that quickly turns brown. It is followed by a more or
less straight corridor of c. 10 mm, entirely filled with greyish
green frass. This suddenly widens into a round blotch that during
its expansion overruns the earlier corridor and in the end may occupy
half of a Laburnum leaflet. The frass, greenish at first,
black later, is deposited in the bloth in roughly concentric arcs,
glued to the upper epidermis. Pupation external, exit slit in upper
epidermis (Bladmineerders van Europa).
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).
larva is illustrated in British
leafminers, UKMoths and Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The larva is described by Patocka (2000a) and Patocka and
Turcani (2005a); rear half of abd. 8 scabrous (difference with L.
genistae) (Bladmineerders van Europa).
pupa is also described in British
leafminers and UKMoths.
The adult is illustrated in UKMoths.
and female genitalia are illustrated by the Lepidoptera Dissection Group.
