How bumblebees find efficient routes without a GPS
Date:9/20/2012

which they learn through trial and error is quite extraordinary for bumblebees as this complex behaviour was thought to be one which only larger-brained animals were capable of," Professor Chittka said.

"Interestingly, we also found that if we removed a flower, bees continued looking at that location even if it was empty for an extended period of time. It seems bees don't easily forget a fruitful flower."

The scientists used motion-triggered web cams and tiny bumblebee-mounted radar transponders to track the bumblebees. The recordings on the flowers showed that bees exhibited considerable individuality each one had a favoured arrival and departure direction, different from the other bees.

Head of Computational and Systems Biology at Rothamsted Research, Professor Chris Rawlings, added: "This is an exciting result because it shows that seemingly complex behaviours can be described by relatively simple rules which can be described mathematically.

"This means we can now use mathematics to inform us when bee behaviour might be affected by their environment and to assess, for example, the impact of changes in the landscape."
