Bumblebees lose sleep looking after the young by napping half as much

January 22, 2019

 

By Chelsea Whyte

In some ways, bumblebees are just like us. When they are tending to their queen’s offspring, they lose significantly more sleep than they do away from the presence of the brood.

In bumblebee colonies, worker bees tend to the queen’s eggs as they move into the larval and then pupal stages before becoming adults. To see if this takes a toll on the amount of sleep the bees get, Guy Bloch at Hebrew University in Israel and his colleagues compared the sleep behaviour of bumblebees during …

 

Active 24/7 And Doing Great

Forager honeybees have a demanding job: Searching for nectar, honeydew and pollen, they permanently commute between beehive and flower meadow. Their circadian clock tells them among others when to arrive in time for the plant to open its flowers and when to rest because potential food sources are "closed".

The circadian clock also helps passing information about good foraging sites to other bees. Because the insects rely on the sun as reference point in navigation, the clock is used at a later time to calculate the flight route.

Bzzzzzz: The Bee’s Need for Sleep

March 8, 2015

Since the 1980s, researchers have known that all insects, including bees, have a form of rest that closely resembles sleep. Just as humans do, bees require rest, despite significant differences in brain size and levels of mental functioning between the two species. In an attempt to explain the same sleep requirement, researchers Ada Eban-Rothschild from Stanford University and Guy Bloch from the Hebrew University of Jerusalem examined the effects of sociability on the sleeping habits of bees.
