Good time to look for the Fen Raft Spider

As he told me, this is the best time to see them as the females tend to sit out in front of the nursery web which she constructs to keep the young spiders safe from predation. So when you find a web with an egg sack, or young spiders in it, and there can be well over two hundred in a web, there should be a large female near by, although you may find them without a web, once there young have dispersed.'
