Sphodrus leucophthalmus is a species of ground beetle native to Europe.Západopalearktický,stenotermní druh Tribu Sphodrini,žijící prvotně v hnízdech větších savců;např.jezevec,liška,.druhotně ve starých sklepích,stájích,komorách a jiných vlhkých prostorách s hliněnou podlahou.Jako potravu upřednostňuje brouky z čeledi tenebrionidae ,a jejich larvy.Velikost dosti kolísá,od 23 do 40 mm.Tento druh byl v minulosti celkem obvyklý,avšak rapidním úbytkem jeho druhotných biotopů,a skrytým způsobem života v prvotních hnízdech savců,se stal velmi vzácným,až téměř vymírajícím elementem.Imaga ponejvíce na podzim,/září ,říjen/.Vzhledem ke skrytému způsobu života je záměna možná s druhy rodu Laemostenus/Pristonychus/, případně s Dolichus halensis/,carabidae:Platynini/,nebo s Pterostichus niger/carabidae:Pterostichini/. Western palearctic, stenothermal species of the tribe Sphodrini, living primarily in the nests of larger mammals; e.g. badger, fox, secondarily in old cellars, stables, chambers and other damp spaces with a clay floor. As food, it prefers beetles from the tenebrionidae family and their larvae. Size it fluctuates a lot, from 23 to 40 mm. This species was quite common in the past, but due to the rapid decline of its secondary habitats and the hidden way of life in the primitive nests of mammals, it has become a very rare, almost extinct element. Imaga mostly in autumn/September ,October/.Due to the hidden way of life, confusion is possible with species of the genus Laemostenus/Pristonychus/, possibly with Dolichus halensis/,carabidae:Platynini/, or with Pterostichus niger/carabidae:Pterostichini
