Common Plaster Beetle
Dienerella filum, known as the common plaster beetle, is a minute fungus beetle in the family Latridiidae. Adults measure 1.2–1.6 mm and are brown in colour. The species has near-cosmopolitan distribution and is strongly associated with human-built environments, particularly damp buildings with mould growth. It is flightless, lacking hind wings, and feeds exclusively on mould hyphae and spores.
