Marsh lousewort is found in central and northern Europe and Asia. In Europe, it occurs in Scandinavia and southwards through most of Europe at altitudes of up to 1,200 m (4,000 ft). In the British Isles, it mostly occurs in Scotland, Ireland, Wales, western England, and East Anglia. In Asia, it occurs in Russia, Kazakhstan, Mongolia, and northern China. Typical habitat is wetlands, swamps, fens, marshes, wet meadows, and ditches.
Marsh lousewort is a semi-parasitic plant, the roots sucking nourishment from adjacent plants. The flowers are pollinated by honeybees and bumblebees; these land on the lower lip, which droops under their weight allowing them to thrust their head inside the flower and extract the nectar, getting powdered with pollen at the same time.
