Continued unseasonably warm weather + unusually high bee activity + no nectar available = check to see if the bees are going through the sugar in the top feeders.
The Gypsy Queen hive. They had not consumed/moved much of the sugar since the last time I looked. BTW, this hive has always been the most aggressive and I immediately got stung on the thumb when I removed the inner cover.
The Gold Bug hive. They have consumed the highest amount of sugar. But, again, not drastically changed since the last time I looked.
The Golden Wonder hive. Again, virtually unchanged since the last check.
The Bonanza Queen hive. As before, they have not touched the sugar.
I did add additional sugar to each of these top feeders since I was in there anyway. I misted the sugar just a bit with warm water to which I had added a couple drops of lemongrass oil.
