Bionomics. Beetles inhabit natural and anthropogenic biotopes, where they live in forest cover, plant remains, under bark of trees, in rotten wood, in mosses, on flowing sap of trees and in nest chambers of small mammals.As facultative mycetobiont, they occur in old and rotten carpophores of fungi.

Distribution. Europe, Caucasus, Asia Minor, North America ( Schülke & Smetana 2015).
