I. Mannerkoski: Ceutorhynchus larvatus Schultze and Ceotorhynchus pallidicornis Gougelet & Brisout de Barneville: on Pulmonaria obscura living weevils in Finland (Coleoptera : Curculionidae). - Entomologica Fennica 11: 245-247.
In Finland two weevil species, Ceutorhynchus pallidicornis and C. larvatus, have Pulmonaria obscura as their host plant. Data on the occurrence of both species are presented and their extremely poorly-known biology is commented upon. Both species are rare but seem to be overlooked in Finland because of their secretive habits.
