Mapping sleep behaviour in bees
As all animals, also bees have to sleep, although this behaviour has not been described in detail for the different castes of bees. Following marked bees, researchers from USA and Germany found that sleeping patterns of bees differ depending on the age and activity of the bees. While older bees sleep in cooler regions in the periphery of the nest and outside of the cells, younger bees sleep in the vicinity of the brood nest and within empty cells. In addition, foragers sleep mainly during teh night, while younger bees sleep both day and night. The functional attributes of these differences though, remain unknown.
