according to Brian Johnson
all social insects spend a great deal of time inactive, often 50% of their day (Hölldobler and Wilson 1990; Johnson 2002, 2003; Evans 2006). There is even data strongly suggesting that many inactive workers are asleep (Kaiser and Steinerkaiser 1983; Klein et al. 2008). Inactive bees are simply stationary and do nothing until they quit their state .
