Habitat
of Ernobiini develop in dead wood, dry branches, and other dry debris. are often found in association with their larval or in buildings where infested wood products are stored.
Distribution
Ernobiini has a broad distribution with records from multiple continents, though specific range limits for the tribe as a whole are poorly documented in literature. Individual show varied distributions: Episernus and Episernomorphus are widespread, while Ernobius and Paralobium have more restricted ranges.
Diet
