Contrary to what you may see on those shoddy “Fun Fact” websites, ants do in fact sleep. Even though they are typically scurrying about whenever we see them, ants often take power naps.
For example, studies have found that queen fire ants fall into relatively long, deep sleeps and kip for an average of nine hours every day. By contrast, workers sleep just half as much and get to rest by taking hundreds of short power naps. This division of rest may help explain why queens live for years, while worker ants typically only live for months.
