At one of my out apiaries the bees were still coming back white striped from the HB, they have been like that for weeks and weeks but no sign of any increase in liquid stores in the hive. They are not bringing any pollen loads back from it and it can't have much of a nectar flow but its obviously all they have to forage on. Bees around Wynyard were bringing in very heavy yellow pollen loads. I presume its Ivy although I can't find any in flower, its all just in bud but maybe the Ivy at the top of the trees (which I can't see) with more sunlight is in flower.
