By 'getting away' we mean 'putting everything ready', being 'cheering', with awake senses and open, sensitive perception. Where does that come from, if they get so lazy? They build their honeycombs slowly, rather than flying they float - like hummingbirds - and the sun reveals the iridescence on their wings. Of course, their colonies are sensitive to nearby presences, and the wasps always monitor their terrain. They may be doing something else, but they are always ready.
