Phyllonorycter anderidae (W. Fletcher, 1885)
[Lepidoptera: Gracillariidae]

Small Birch Midget

Lithocolletis anderidae W. Fletcher, 1885. Ent. mon. Mag. 22: 40.
Phyllonorycter anderidae
(W. Fletcher, 1885).

Leaf-miner: A small mine (about 1cm long), which strongly arches the leaf. The mine of Parornix betulae can appear similar, but the underside becomes brown whereas the mine of P. anderidae stays green (British leafminers).

Small lower-surface tentiform mine; epidermis pale green, rather weakly folded. The pupa lies without a cocoon in the mine (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).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

The cremaster is illustrated in British leafminers and Bladmineerders van Europa.

Adult: The adult is illustrated in UKMoths. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
