Phyllonorycter kleemannella (Fabricius, 1781)
[Lepidoptera: Gracillariidae]

Dark Alder Midget


Tinea kleemannella Fabricius, 1781
Phyllonorycter kleemannella
(Fabricius, 1781).


Leaf-miner: The mine is underside, small, seldom reaching midrib. The lower epidermis with several small creases, sometimes several larvae mine the same leaf (British leafminers).

Lower-surface tentiform mine between two side veins, often at quite some distance from the midrib. Lower surface with many folds, all very weak. Often several mines in one leaf. Pupa in a white cocoon in an angle of the mine, attached to the roof. The cocoon is free from frass; all frass is heaped in an angle of the mine, opposite to the cocoon (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 Bladmineerders van Europa.

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).
