Phyllonorycter quercifoliella (Zeller, 1839)
[Lepidoptera: Gracillariidae]

Common Oak Midget


Lithocolletis quercifoliella Zeller, 1839. Isis: 217.
Phyllonorycter quercifoliella
(Zeller, 1839).


Leaf-miner: The mine is medium (>10mm) or large, single crease in lower epidermis. The frass surrounds cocoon in summer, but in U-shaped lining in autumn (British leafminers).

Lower surface tentiform mine, variable in size, (10)-15-(22) mm. Lower epidermis with one sharp fold. Pupa in a tough silken cocoon in the mine. In the summer generation the cocoon is entirely covered with frass, and the cocoon is attached to the roof of the mine only. In the autumn generation frass in incrusted only to the sides and rear of the cocoon, and the cocoon is attached both to the roof and the floor of the mine (Bladmineerders van Europa).

The 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).

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 species is included in mothdissection.co.uk.
