Raft Spiders
Scientific name: Dolomedes fimbriatus Size: 9mm to 20mm Distribution: Found throughout the U.K., but locally distributed Months seen: May to August Food: Tadpoles, insects and small fish Habitat: Marshes, swamps and ponds Special features: Sometimes called the Fishing Spider or Fen Spider. The Raft Spider sits at the edge of pools with its front legs resting on the surface of the water. From this position it can detect the vibrations made by any small creatures as they touch the water. Using the surface tension of the water it can run across the surface to catch its prey. When alarmed the raft spider can dive under the surface of the water and remain submerged for several minutes.
