Phyllonorycter comparella (Duponchel, 1843)
[Lepidoptera: Gracillariidae]

Hartig, 1952. Boll. Ass. Romana ital. 7: 17, fig'd.
Phyllonorycter comparella
(Duponchel, 1843).


Leaf-miner: An underside mine, with few creases and causing little leaf distortion. Some mottling of the upper leaf surface may be caused (British leafminers).

Oval, lower-surface tentiform mine. The lower epidermis has no recognisable folds, and in fact the mine is barely visible in the felty underside of the leaf. Frass heaped in an angle of the mine. Pupa in a barely recognisable flimsy cocoon (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).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

The cremaster is smooth and rounded, with tiny spines (British leafminers).

The pupa is also illustrated in Bladmineerders van Europa.

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