do insects sleep? Mammals do, birds do, heck even reptiles do. But do small bugs like crickets sleep?

they do sleep, and the exception for reptiles and everything needing sleep is fish, the don't sleep. they kinda go into a neutral mode, but its hind of hard to sleep when you don't have eyelids:(

Yes but unlike humans they need only 1 hour of sleep, but mostly while they are sleeping they get killed soo ya
