It features a quadrangular head, short space between the eyes, and a toothed posterior pronotal edge.

Observed from April to September, peaking in May, it is polyphagous on over 20 plant species, mainly found on clovers and melilotus.

Adults and nymphs overwinter in leaf litter or moss, with eggs laid in June-July and a new generation appearing mid-July to mid-September.

It is native to Western Europe, extending to the Ural Mountains, Turkey, Israel, and North Africa, favoring dry, sandy areas, forest edges, and sunny, warm locations.

[2] The species was originally described by its basionym Cimex denticulatus by Giovanni Antonio Scopoli and is now classified under the genus Coriomeris.
