Bumble bees make a beeline for larger flowers

Bumble bees create foraging routes by using their experience to select nectar-rich, high-rewarding flowers. A study by Shohei Tsujimoto and Hiroshi Ishii of the University of Toyama in Japan now suggests that bees actually forage more efficiently when flower sizes are large rather than small. This indicates that for these insect pollinators foraging quickly is more efficient than foraging accurately. The research is published in Springer's journal Behavioral Ecology and Sociobiology and uses a laboratory-based experiment to investigate how aspects of associative learning influence how bumble bees find food among different-sized flowers.
