Have you been wondering whether busy honey bees ever sleep?
Most foragers sleep at night from 5 to 8 hours after their hard day’s work and occasionally nap briefly on a flower during daylight. They are the oldest bees in the colony except for the queen.
Younger adults working inside the perpetually dark hive take short naps at any time during their 24-hour day, and need less sleep overall than their older nestmates do.
When they do sleep, it is often inside cells close to the center of the nest. But sometimes several cluster with their feet clasping those of their companions, as if “holding hands” as they snooze at the quiet edges of frames.
Honey bees are not alone in their need for beauty rest–other bees have been caught catching forty winks, too, often in endearing poses in a petal-bed: see a fuzzy bumble bee dozing on a dandelion, or a pair of native globe-mallow bees dreaming inside the mallow blossom where they were gathering nectar.
How would you recognize a sleeper? It’s the only time you may see a bee’s antennae completely still, lowered and at rest, while the head and body are also relaxed with no movement at all.
And the longer or more deeply the little insect sleeps, the harder it is to waken—can you relate?
