Trichiosoma lucorum
Reasonably common in Britain and Ireland. 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.
Larvae feed on birch.
Size: 13 - 24mm
