Pterostichus strenuus (Panzer, 1796)

Description: 5-7mm long black ground beetle. Predatory. Very common in almost every habitat, usually living among plant litter but also under stones. Common in gardens and on arable land.

World Distribution: A Eurasian Wide-temperate species (65) distributed across the whole of Europe except the extreme south, and east into Siberia as far as the River Amur.

Irish Status: Widespread and abundant.

Ecology: Eurytopic, but much more a species of cultivation than P. diligens, although they frequently occur together in marshes. Best distinguished by the widely spaced, but strong puncturation of the prosternum.
