Looking round the garden on a cold wet July evening(!) I found dozens of cuckoo bumblebees (probably Bombus vestalis or B. bohemicus) sleeping on or under the flowers of Cirsium rivulare, one of their favourite food plants.
These cuckoo bumblebees were sleeping in Astrantia.
Also sleeping out in the rain were male early bumblebees (Bombus pratorum) who had no home to go to.
And a worker common carder bee (Bombus pascuorum).
I was surprised to find only one bee asleep in the foxgloves, a garden bumblebee (Bombus hortorum). I would have thought foxgloves would provide a perfect weather-proof bivouac but the bees seem to favour sleeping on their preferred food plants.
In the morning I could find common carder bees and garden bumblebees chilled and covered in dew.
Flying around, sipping nectar and chasing females all day sounds like a great life but it is not all fun and games being a bumblebee.
