Phyllonorycter coryli (Nicelli, 1851)
[Lepidoptera: Gracillariidae]

Nut Leaf Blister Moth


Lithocolletis coryli Nicelli, 1851. Stett. ent. Zeitg. 12: 36.
Phyllonorycter coryli
(Nicelli, 1851).


Leaf-miner: The mine is upper side, over veins. Silvery, with brown speckling, later contracting to cause leaf to fold upwards. There may be several mines on each leaf (British leafminers).

Upper-surface silvery tentiform mine. For some time the mine remains quite flat, and appears as a blotch mine. In the final stage the leaf is strongly contracted, however. Not infrequently several mines in a leaf. Pupa in a cocoon in a corner of the mine, frass heaped in the opposite corner (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).

Cremaster has four hooked precesses - the outer pair being broader than the inner ones (British leafminers). The pupa is illustrated in Bladmineerders van Europa.

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

Time of year - larvae: July, September - October (British leafminers).

Time of year - adults: Being bivoltine, the adults are on the wing in May and again in August (UKMoths).
