Trichiosoma lucorum

Reasonably common in Britain and Ireland. Description follows Zhelochovtsev (1988). Males cannot be reliably distinguished from Trichiosoma laterale at present. The female is black on the abdomen and lacks any reddish-brown laterally or beneath. On the apical tergites, the silky, adpressed pubescence does not obscure the underlying puncturation.

Trichiosoma lucorum larvae feed on birches and willows.
