Where do they go?

We have planted our garden with a range of plants that are insect friendly- at different times of the year they provide nectar and pollen. So, at the top of the garden live our bees- the garden is full of butterflies, bumble bees ,hover flies and other ,mostly welcome insects. But hardly ever have we seen honey bees foraging around the garden, just the odd one on the buddlea or golden rod. So where do they go? Maybe the answer as Rob (picture courtesy of sustainablegarden.blogspot.com) suggests is the allotment. The borage, lavender and other herbs have recently been visited by honeybees in abundance-in theory the distance is within range; so maybe this is where they are doing their good work!!
