They Sleep. They sleep whenever they feel sleepy.
Do spiders sleep?
It really depends on how you mark out "sleep". All animals have some sort of 'circadian' rhythm - a day after day activity/inactivity pattern. Some are involved during the day - diurnal - others are stirring at night time - nocturnal/crepuscular. The period of inactivity are characterised by subtraction (to a shelter perhaps) and a drop in metabolic rate.
This applies to spiders as in good health, although no studies have be done to measure the time of year of time spent in such a state or at what times different species do it. It seem that spiders with apt eyesight that rely on vision to invasion prey may tend to be more active contained by daylight hours, whereas others that rely on snares/webs could be involved at other times, but this is not necessarily the case for adjectives species.
In cold climates, spiders "overwinter", which means that they own a kind of hibernation time. Overwintering involves a drop in metabolic rate, where on earth the spiders bring their legs into their body and remain huddled in a shelter during the coldest months of the year.
This propensity to shut down for a long period of time indicates that they might be capable of do it for shorter periods surrounded by their everyday cycle, which could be seen as a form of sleep or rest.

It really depends on how you define "sleep". All animals hold some sort of 'circadian' rhythm - a daily activity/inactivity stencil. Some are active during the daylight - diurnal - others are active at hours of darkness time - nocturnal/crepuscular. The periods of indolence are characterised by withdrawal (to a shelter perhaps) and a drop surrounded by metabolic rate.
This applies to spiders as well, although no studies own been done to weigh up the period of time spent within such a state or at what times different species do it. It seems that spiders beside good eyesight that rely on delirium to capture prey may tend to be more stirring in daytime, whereas others that rely on snares/webs could be active at other times, but this is not necessarily the valise for all species.
In cold climates, spiders "overwinter", which manner that they have a considerate of hibernation period. Overwintering involves a drop within metabolic rate, where the spiders bring their legs into their body and remain huddled within a shelter during the coldest months of the year.
This ability to shut down for a long time of year of time indicates that they might be able to do it for shorter period in their everyday cycle, which could be see as a form of sleep or rest.
Yes. but they awaken fast when they detect movement on the pattern. they are predators after all.
