We've hit a nectar dearth here. I just picked up a new nuc last Thursday and the inspector said it needed feeding. All three of my hives are now back on syrup and taking it eagerly. They continue to work crown vetch but that's about the only thing blooming in abundance for us at the moment.
One of the hives made supercedure cells recently (the queen was alive but apparently failing) and is making a new queen (I hope). We've noticed that the foragers from that hive are not bringing in pollen at all. Another hive still has a productive queen IS bringing in some pollen, although not like the first few weeks. I asked my bee supplier about this just today and he says that's normal. He does not even carry pollen patties this time of year, and said not to worry, there is pollen out there if they want it.
BTW, other than the hive with the failed queen, we've seen only a couple of empty queen cups. They have plenty of room. Our return to feeding was based on inspections showing they still needed to draw comb and their stores appeared sparse, reinforced by the opinion of the state bee inspector, and then again today by our bee supply guy. The bees got the final vote ... they were eager for syrup.
