Trichiosoma laterale

Rarely found in Britain and Ireland. Occurs sporadically in Scandinavia. Very similar to the commoner Trichiosoma lucorum and vitellina. Trichiosoma laterale may be overlooked by confusion with the other two. Trichiosoma laterale is mainly black but more or less reddish-brown laterally. On the apical tergites, the silky, adpressed pubescence does not obscure the underlying puncturation.

Larvae feed on birch and willow.
