We had one cold snap here earlier this month (a snowstorm, highs in the low 30s, lows in the teens for a week), and mild temps (40-50/20s) before that, and progressively warmer temps the last 2 weeks (60s/20s-30s).
Checked them the other day and they had used hardly any of the sugar, were clustered in the center of the single deep right under the inner cover's vent hole. I had spread a little bit of sugar along the top bars, and surprisingly, they hadn't even cleaned that off, as far as I could tell. But they were mean as junkyard dogs when I opened the hive up. So, I pulled out an end frame with (empty) comb, tossed in a feeder, and poured in 1 liter of 2:1 syrup.
I wish I had a better handle on how bees manage their stores, although I read recently that they use 80% of their stores in the last 20% of winter, which is odd- you would think it is temperature dependent and that they use more in mid-winter and less in the milder early/late winter periods. Do they only go for the sugar if they are completely out of stores? Are they able to feed on sugar during the warm days, then keep the hive warm during cold nights even when there is no honey? Does syrup that is fed in a warm period such as now go into cells, or do the bees just suck it down immediately?
