Phyllonorycter sorbi (Frey, 1885)
[Lepidoptera: Gracillariidae]

Rowan Midget


Lithocolletis sorbi Frey, 1885. Mitt. Naturf. Ges. Zürich.: 608.
Phyllonorycter sorbi
(Frey, 1885).


Leaf-miner: A large mine with a strong crease in lower epidermis. Leaf-edge often folded downwards (British leafminers).

Lower-surface, yellow-green tentiform mine with a few sharp folds in the epidermis. In Rowan the mine is parallel to the leaf margin, in Cherry usually between two lateral veins. The light brown cocoon lies in a wide cocoon, in which no frass is incorporated; all frass is accumulated in a clump in an angle of the mine. Before hatching the pupa penetrates the mine wall; generally the exuvium remains stuck halfway out 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).

The larva is illustrated in UKMoths.

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 male and female genitalia are illustrated by the Lepidoptera Dissection Group.
