Phyllonorycter stettinensis (Nicelli, 1852)
[Lepidoptera: Gracillariidae]

Small Alder Midget


Lithocolletis stettinensis Nicelli, 1852
Phyllonorycter stettinensis
(Nicelli, 1852).


Leaf-miner: The mine is upper side, oval, over midrib or side-vein - the upper epidermis flimsy with one strong crease (British leafminers).

Unlike other species that form an upperside mine, the surface is not papery, but quite glossy and heavily creased. The mine begins green and then turns orange or brown when more mature (UKMoths).

Upper-surface, fairly small, almost flat tentiform mine with a characteristic yellow green colour. The mine has a single, moderately strong, fold. Generally the mine is positioned over a lateral vein. Frass in a clump in a corner of 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).

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

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

The pupa is formed in a white cocoon (British leafminers).

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