What is the widely believed but mistaken idea associated with the common name 'Raft Spiders'?
Answer
That they construct floating platforms or rafts for travel
The name 'Raft Spiders' often leads to a common misunderstanding regarding the locomotion methods of *Dolomedes* spiders. The perception is that these arachnids actively build or weave a physical floating platform or raft made of silk or debris upon which they rest or travel across the water. In reality, they do not construct such structures. Their ability to remain on the water is purely passive, relying entirely on the inherent physical properties of the water, specifically the natural surface tension, which their water-repellent hairs allow them to exploit for movement.
