Phyllonorycter salicicolella (Sircom, 1848)
[Lepidoptera: Gracillariidae]

Long-streak Midget


Argyromiges salicicolella Sircom, 1848. Zoologist: 2271.
Lithocolletis brevilineatella
Benander, 1946. Opusc. ent. 9:108, fig'd.
Phyllonorycter salicicolella
(Sircom, 1848).


Leaf-miner: The larvae feed in a blotch on the underside of a leaf of sallow, causing the leaf edge to curl under when at the edge (UKMoths).

Fairly small, lower-surface, tentiform mine, often toching the leaf margin. The reddish brown pupa in a flimsy, whitish of very pale yellowish cocoon; possibly the cocoon sometimes is missing altogether. Frass packed in a corner of the mine (Bladmineerders van Europa).

Cannot be separated (without opening mine or breeding moths) from mines of other sallow-feeding species (British leafminers).

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 pupa is illustrated in Bladmineerders van Europa.

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
