As a bumblebee colony is nearing its peak attention turns to rearing the next generation of bumblebee queens and the males to mate with the queens from other nests. When these bees leave the nest they do not return so will need to find food and shelter themselves and many use our gardens to do so.
Often people will spot a bumblebee sitting around, a bit slow moving and drowsy and assume the bee is ailing from something or in trouble. In most situations that is not the case. Between feeding and mating activities they will often bask in the sunshine, finding a spot to have a rest or become chilled if the weather takes a turn, or can be found sheltering under a flower in the rain looking very sorry.
This is perfectly natural, and when the sun comes out again they dry off remarkably quickly and continue doing what they were doing, often wandering to the top of the flower they were sheltering under for a convenient top up. So next time you see a grounded bee or a bee sitting out the rain underneath the flowers unless it is in extreme danger of being trodden on just watch, they often take the opportunity to have a quick groom before they set off again which is lovely to observe up close.
