Incurvaria pectinea Haworth, 1828 [Lepidoptera: Incurvariidae]. Incurvaria pectinea Haworth, 1828. Lep. Brit.: 559. Tinea zinckenii Zeller, 1839.

Leaf-mine: 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). Mines of Incurvaria pectinea on Alnus glutinosa Image: Willis (Bladmineerders van Europa) The mine is also described and illustrated in British leafminers. Larva: The larva is described and illustrated in British leafminers and Bladmineerders van Europa. Pupa: Details unknown. 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.
