Too much sugar in nectar slows down bees, a study has found.

Bumblebees offload the nectar they drink from flowers by vomiting, but the more sugar nectar contains, the thicker and stickier it becomes – meaning it takes more time and energy for the bees to regurgitate it.

A report, published in the Journal of the Royal Society Interface, looked at both stages – drinking and vomiting – in one of the most common bumblebees in the UK, the Bombus terrestris (or the buff-tailed bumblebee).
