The 3.5 to 4 mm large hairy fungus beetle Triphyllus bicolor (family Mycetophagidae) is known to occur in Central and Southern Europe as well as in the southern regions of Northern Europe. In the east, its range reaches Western Russia. In Germany, Triphyllus bicolor is recorded from all Federal States, however, it is generally regarded as rare. The stenotopic, silvicolous species is mycetobiont and develops on soft fleshed agarics on decaying wood of deciduous trees, especially oak (Quercus) and beech (Fagus). There seems to be a preference for the beefsteak fungus (Fistulina hepatica). Both beetles and larvae feed on fungal hyphae and spores. For pupation, the larvae dig themselves into the ground. In the Red List of Germany Triphyllus bicolor is classified as vulnerable (RL 3). (CB)
