Flowers “wave” to attract bees.
It has long been known that insects are attracted to pollinate flowers by their bright colours and sweet scents. But now a report by Welsh scientists in the Journal of Evolutionary Biology shows that long stemmed flowers which display more movement attract a wider variety of insects.flower_and_bee.jpg

The study analysed the number and types of insects that landed on each of several varieties of flower, and correlated that with how much or how little that variety was generally swayed by the wind.
Short, fat-stalked flowers don’t wobble enough and are less attractive to pollinators; yet very wobbly flowers are just too wobbly for the insects to handle, as the insects cannot land on them.

Flowers need to wobble just the right amount to be successful in setting seeds.
