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

Western Midget

Lithocolletis muelleriella Zeller, 1839. Isis: 217.
Elachista amyotella
Duponchel, 1840. Hist. Nat. Lep. 11: 544.
Phyllonorycter muelleriella
(Zeller, 1839).

Leaf-miner: Lower-surface tentiform mine, generally rather small and between two veins, touching the midrib. Lower epidermis with a single sharp fold. Pupa in the mine in a cocoon that with its upper- and lowerside is attached to the mine; almost all frass is incorporated in the sides of the cocoon (Bladmineerders van Europa).

The mine is also illustrated in 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).

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.
