Flowers come in many different shapes and sizes, so when a bee is looking for nectar, what sort of flowers are they making a beeline for?

Bees and their tongue lengths

Different types of bee have evolved to have different tongue lengths, this means that they are not all competing with each other to feed from the same flower shapes.

Long-tongued bees can feed from flowers shaped like tubes such as snapdragons, which have their flowers arranged in racemes (see flower spotter guide number 9 below) to reach their nectar reward.

Short-tongued bees, on the other hand, need their nectar to be easier to reach and prefer open flowers, like clover. Some short-tongued bees have learned to ‘steal’ nectar from tube-shaped flowers by nibbling a hole at the base of the flower and feeding from the outside. Have a look at the photo to see one in action.

Other bees have a medium-length tongue, for example the red-tailed bumblebee; this means that they are able to feed on lots of different flower shapes.

It can take time for bees to learn how to get to nectar from more complicated flower shapes, such as trumpet shaped flowers (see number 15 in the spotter guide below).

When you think about which plants to put in your growing space, it is a good idea to have lots of different flower shapes available, so that there is nectar available for different types of bees.

Quiz question

Can you work out from the spotter sheet which flowers are not as good for hungry bees looking for nectar? (Find the answer at the end of this article).

The Bee Garden at St George's Primary School

The pupils at St George’s Primary School, Camberwell, had a look around the Bee Garden at their school to see which flower shapes they could find. They spotted these beautiful flowers, which have a cruciform shape, see number 5 in the flower spotter guide above.

Answer to quiz question

The flower shapes which are not as good for hungry bees are: double (number 7) and pompom (number 8). This is because they have many layers of petals, making it difficult for bees to get past the petals to the nectar that they need.
