The 3.5 to 4 mm large Mycetophagus quadriguttatus (family Mycetophagidae) is one of ten representatives of the genus in Germany. Some of the species resemble each other quite a bit. However, they can be distinguished by their habitus, coloration and by the form of the club of the antenna. The latter is four-segmented and the last segment is barely longer than the second last in Mycetophagus quadriguttatus. The species occurs throughout the holarctic and lives in deciduous forests in mouldy detritus and brushwood of oak (Quercus), beech (Fagus) and on agarics as well as synanthropic in barns and stables in mouldy hay and straw and on moulding foodstuffs. Both adult beetles and larvae feed on mould fungi and their spores. In Germany, Mycetophagus quadriguttatus is currently recorded from all Federal States and is regarded as not endangered.
