Betula pendula Ectodemia occultella 34 Lepidoptera found in the Wyre Forest

138 Lampronia fuscatella

(Tengström, 1848)

Wingspan 14-18 mm.

The adults of this species, unlike some of the otherLampronia species, are relatively plain in appearance.

The moth is quite local in Britain, occurring scarcely in a few widely scattered localities throughout. It flies in May and June, during the afternoon.

The larva is unusual in that it forms a swelling, or gall on a twig of birch (Betula), usually at a node, within which it feeds. The presence of reddish-brown frassaround the exit hole indicates a larva within.
