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

Small Elm Midget


Tinea schreberella Fabricius, 1781. Spec. Ins. 2: 304.
Phyllonorycter schreberella
(Fabricius, 1781).


Leaf-miner: The mine is oval, sometimes crossing veins. The lower epidermis with several strong creases (British leafminers).

Along with P. tristrigella, this species feeds on elm, although not usually on wych elm like that species. However the two mines are quite different - schreberella forming a rounded mine and tristrigella a longer, narrower tube-like mine (UKMoths).

Short, roundish to oval, somewhat inflated, lower surface tentiform mine, often crossing a lateral vein. Epidermis with several length folds. 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).

Dark brown pupa in a tough, greenish cocoon; the cocoon lies free in the mine, and its wall is not encrusted with frass (Bladmineerders van Europa). The cremaster is illustrated in British leafminers.

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