Where do spiders get water from?

Some Spiders get most of their water from their prey, but if a spider is thirsty and there is a drop of dew it will suck up water from the drop. If there is a little trickle of water running down a stone they will get their mouth down close to the stone and drink their fill. If they find a puddle of water they will drink from that. Some spiders are adapted to live around streams, or even to live under water. So those spiders will very easily get water from any large body of water.
