description Dolomedes plantarius Overview

Dolomedes plantarius, commonly known as the fen raft spider, is a large semi-aquatic species of nursery web spider found in Europe. It is distinguished by its ability to hunt on the surface film of water in wetland habitats, preying on insects, small fish, and tadpoles. The species relies on undisturbed fenland and grazing marshes, making it vulnerable to habitat loss. Conservation programs in the United Kingdom have been established to protect and reintroduce this rare spider into its native wetlands.
