The weather this past weekend was beautiful and I decided to check my hive. The temperature was supposedly around 10 degrees Celsius, but it felt a bit cooler than that. To play it safe, we did not open the hive more than just the outer (AKA telescoping) cover.
The good news is that as of March 30, 2013, I still have bees! (Although I don’t want to speak too soon.) I won’t yet consider this a successful “overwinter” until there is lots of forage available and I’ve seen the next generation of worker born and working.
The bees are still clustered at the top of the hive, and those that are making cleansing flights are doing so from the ventilation that I added in the fall, instead of the lower entrance. I guess that’s OK. I’m willing to bet they’ll return to the proper entrance once things pick up in a few weeks.
