Fleshy fungi of the genera Armillaria, Pleurotus, and Grifola as habitats of Coleoptera

Abstract

The paper deals with adult beetles attracted by wood-rotting agarics of the genera Armil-laria and Pleurotus, plus those collected on the oak-decaying polypore Grifola frondosa. The interrelations of 14 species (110 samples) of fungi and 78 species (1691 individuals) of beetles are discussed. More close relationships, such as fungivory of larvae of Coleoptera are also treated. In southern Finland larvae of Cychramus (in Armillaria) and Triplax (in Pleurotus) are able to utilize fl eshy wood-rotting fungi. The majority of beetles were recorded as adults, including 52 (67%) species of Staphylinidae.
