Incurvaria pectinea Haworth, 1828
[Lepidoptera: Incurvariidae]

Pale Feathered Bright


Incurvaria pectinea Haworth, 1828. Lep. Brit.: 559.
Tinea zinckenii Zeller, 1839.


Leaf-miner: The larva starts making a corridor of a few mm, followed, and mostly overrun, by a circular blotch of 4-5 mm diameter (Bladmineerders van Europa).

Generally several larvae feed in a single leaf, creating a distinctive pattern of feeding windows. The larvae then cut out circular cases and drop to the leaf-litter to continue feeding, leaving behind a leaf containing many circular or oval cut-outs (UKMoths).

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).

The larva is illustrated in British leafminers and Bladmineerders van Europa.

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

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. The ovipositor comb of pectinea is illustrated in British leafminers alongside oehmanniella and masculella.
