Despite the dismal weather we had last Saturday, people from various walks of life gathered at the Sutton Ecology Centre for the Biodiversity Gardens workshop ‘Bees for Beginners Training Day’. Guest speaker David Pinnock, a long term volunteer for the Bumblebee Conservation Trust (BBCT), led the day with an interesting talk on bumblebees, which covered their ecology, identification and the work of the BBCT.

Common carder bee

We have many different types of bees in the UK, which include bumblebees, solitary bees and a single species of domesticated honeybee. Although they may all look superficially similar, bumblebees are distinguished by being much larger and fluffier than the other bees. We have 24 species of bumblebee in the UK, 8 of which are commonly seen, so if you’re struggling to identify a bee you can make a good start by looking at these top 8:

  1. Buff-tailed bumblebee (Bombus terrestris)
  2. White-tailed bumblebee (Bombus lucorum)
  3. Garden bumblebee (Bombus hortorum)
  4. Early bumblebee (Bombus pratorum)
  5. Common carder bee (Bombus pascuorum)
  6. Red-tailed bumblebee (Bombus lapidarius)
  7. Tree bumblebee (Bombus hypnorum)
  8. Heath bumblebee (Bombus jonellus)
Bumblebees actually live very interesting lives, they are hard-working, organised and certainly stick true to phrase “keep it in the family”. They live in social groups referred to as ‘colonies’ which can be made up of up to 400 individuals, including a single queen, her workers and some males. Only the queen produces offspring, so all bee species in a colony are either sisters, brothers or the queen herself! This is interesting as on first glance it seems to conflict with Darwin’s idea of ‘survival of the fittest’ as fitness is measured in terms of offspring produced. So surely natural selection would favour workers who reproduced themselves? The answer is no, because natural selection works at the level of the gene, and workers share their genes with the queen. Therefore workers are actually ‘fitter’ by investing their energy in the survival of the colony, a phenomenon known as ‘kinship selection’. For more information on the social lives on bees then visit where you can download a free copy of ‘An introduction to bees in Britain’ compiled by Robin Williams.
Unfortunately bees have had a lot of press coverage over recent years because of the dramatic decline in their numbers. Many of the flower-rich meadows which bees rely on for food and nesting have been replaced with agricultural fields which do their very best to reduce the ‘weeds’ which bumblebees need for survival. Bees are an excellent example of why wildlife is important to people, as their role in our ecosystem depicts what conservationists’ term ‘ecosystem services’. Ecosystem services is basically a fancy term used to describe the benefits we receive from wildlife, whether it is purely aesthetic, or because wildlife provides us with some kind of service we depend upon such as crop pollination. Everybody knows that bees pollinate flowers, but did you know that bumblebees are the sole pollinator of tomato plants, and without them we would not have any of the tomato-based food products which are so popular in our diets? It’s not just tomatoes we would lose without bees either, many of our cereals and fruit would cease to end up on our plates without the helping hand of pollination from bees.
By providing this workshop, we have hopefully inspired people to take a greater interest in bees and understand their importance to us. Everybody can help bees by simply having bee-friendly plants in their garden, or go further by creating a wildflower meadow. The great thing about helping bumblebees is that you are also indirectly helping other insects such as butterflies which utilize the same habitat.
Our next workshop will be ‘Trees for Beginners’ on Saturday 21st September, to book a place visit here.
