Sporophores of Piptoporus betulinus (Bull. ex Fr.) Karst. and Fomes fomentarius (L. ex Fr.) Kickx were collected during March to December 1991 from five different West Norwegian forests. Their beetle faunas are described in detail. Various factors contribute in the decomposing process of the sporophore, and the faunas change considerably during this process. The host specificity of the obligatory polypore inhabitants is probably determined by other factors besides the polypore itself, because the faunas change between forests of different productivity classes and with different tree compositions. Furthermore, the almost vicariant distribution of Cis alter and C. jacquemarti could best be explained by interspecific competition. A simple phenology for Cis bidentatus, C. alter, C. lineatocribatus, C. jacquemarti, Leptusa pulchella, L. fumida and L. ruficollis is given.
