Bumblebees

Spring and summer are a great time of year to get outside looking for bumblebees.

Queen bumblebees spend the winter asleep in little burrows. In the spring, she emerges and starts to look for food to build up her reserves from a winter of not eating! Once she is ready she starts looking for a nesting site. This could be in some long grass, a hedgerow bank or even an old mouse hole. Once she is happy with her chosen site she starts to collect pollen which she makes into a “Bee Bread” by mixing it with nectar. She lays some eggs in her nest and once the little grubs hatch they feed on the bee bread.

Once the grubs are big enough they will pupate (just like a caterpillar) and soon new worker bees will emerge. The queen now stays in nest laying eggs, while the workers do all the work of collecting the pollen and looking after the young.

In early summer, it is often the workers you see feeding on flowers. Sometimes you will see a queen. These tend to be much bigger.

Look out for the full pollen baskets on the back legs of the bees. The one below is very full!

Later in the summer new males and queens will emerge from the nests. They will mate. The new queens will feed and build up their reserves before they hibernate and start the whole cycle all over again.

  1. I was only wondering this morning while gardening what the life cycle is of bumblebees, I saw several on my comfrey plant, some were small and one was large, they had been working hard by what I have just learnt from you. Great, I can tell my grandchildren that too. Such wonderful creatures! Thanks for info.

    1. Glad it was so timely. Here too we still have a few Queens about but not as many as a few weeks ago. Now it is mostly the smaller workers
