Platynus assimilis (Paykull, 1790)

Description: A moderate-sized (8.5-12mm), long-legged, black ground beetle. Common found under bark in wet woodland and general in scrubby marshes and fens.
 

World Distribution: A Eurasian temperate species (75) distributed across most of Europe, south to northern Spain and Italy, and east into Siberia as far as the Lena.
 

Irish Status: Widespread and usually abundant in its habitat.
 

Ecology: Stenotopic for wet woodland and carr, and becoming commoner in recent years, sometimes spilling over into other habitats. Characteristic of wet alder woodland in river valleys or lakeshores, where it is common hibernating under the bark of dead standing timber.
