Bees find their way back to hive up to 13 km away: scientists

Bumblebees' internal homing device may extend much farther than British scientists originally thought.

Researchers from Newcastle University conducted a study to see how far the bees travel before being unable to come home.

The scientists tagged about 100 bumblebees with tiny identification numbers and then dropped the bees in different locations around Northeast England.

The results showed that the bees within 13 kilometres of the hive were able to return back safely.

Although only 20-30 per cent of the bees returned, scientists say other factors like predation could explain the missing 70-80 per cent.

As well, some bees may have considered the journey too tiring, particularly the Queen bee, which is not used to a working colony lifestyle.

Researchers say the Queen bee attempted to return home but eventually remained in one location to prepare for hibernation.

Scientists speculate that the bees used their ultraviolet vision to recognize landmarks to help them come home.

The researchers eventually hope these results will aid conservationists in creating an ideal bumblebee habitat, as pollinating bees have been declining in the area.
