Well Queens do, usually for several hours. Normal ants get by on a few naps or periods of rest per day. They only sleep briefly as they only have a very short lifespan and as it is in colony, the time is used to work instead. Queens are believed to live much longer due to the fact that they get to sleep!
Also importantly, their ‘sleep’ isn’t like ours, it’s more like a rest period than what we go through.
