Winter Aconites are one of my favourite flowers and the bees like them too. We have a large patch of them right outside our back door. Despite very frosty nights there has been a little warmth in the sun during the day and this spot gets the sun full on it by mid morning. Yesterday a few bees were stretching their wings and enjoying what the Aconites had to offer. One of them looks as if it is about to curl up for a snooze in one of the flowers in the fourth photo.
