Description:
One British genus, Hydrochus, containing 7 species of crawling aquatic beetles. Generally sluggish, they play dead when disturbed and are correspondingly difficult to find in the field. Adults are elongate, with heavily-pitted elytra and pronotum, and are most often found in plant litter in well-vegetated ponds and bogs.
