Incurvaria pectinea: Distribution map

Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

As soon as a replacement map service is available, distribution maps will hopefully appear here again.

In the meantime, you can get some idea of distribution from the NBN Atlas website.

8.001 BF129
Incurvaria pectinea

Haworth, 1828


Wingspan 12-16 mm.

The adults of this species are similar in appearance to I. masculella, but rather less contrastingly-patterned.

The antennae of the male seem to taper more abruptly near the tip than the more gradual narrowing of that species. Flying in April and May, the species is fairly well-distributed throughout much of the British Isles, though tends to be commoner further north.

The eggs are laid on leaves of birch (Betula), hazel (Corylus) or occasionally hornbeam (Corylus) or apple (Malus). 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.
