  I don’t like spiders… They are in general nocturnal hunters. Which is odd as flys are day time insects. However I do know that spiders have poor eye sight even though they have 8 of them. The respond to light, heat and vibrations. They are more active at night as their predators are generally asleep at night too.

  Like Bob says, most spiders are notcturnal – they hide themselves away during the day, down cracks and in really small spaces where we never notice them.

  Yes, they’re nocturnal. In the house they live in corners, little holes in the wall, or under furniture, but in the Amazon the tarantulas have sort of nests/holes in the ground. I was in the jungle at night and the guide pulled one out of a hole so we could see it. It was bigger than my hand!

  A spider can squeeze itself into the tinest of cracks so it can’t be seen. I think they come out at night as they have learnt that they can build their web undisturbed and then lie in wait during the day when all the flies and other tasty insects appear and wait for breakfast.
