Further to my previous post which included Raft Spiders I revisited the New Forest stream where we found several of these interesting arachnids. We found 7 Raft Spiders today including a juvenile spider and a female with an egg sac.
Raft Spiders will carry their egg sac around for some time before creating a nursery web for their spiderlings. (Last time we found a nursery web.)
These large spiders will sit at the edge of the water, or on floating vegetation, with their front legs resting on the water’s surface in order to feel for the vibrations of potential prey, they chase out onto the water to catch their prey, ranging from tadpoles or small fish. They will also swim underwater.
