One aspect of top bar hives (TBH) I enjoy is watching the bees build comb. You just don’t really get this in Langstroth hives, especially when using foundation. I caught a couple of pictures of the bees building comb last week, and though they were worth sharing.
Bees building comb at the back of my hive Jupiter 2 on April 16, 2022. The bees build an oval that expands to fill the hive. There is a small comb on the left that the bees have started as well, which they will eventually join with the other.A top bar hive frame on April 16, 2022. The cells are mostly filled with nectar. Note how the bees put a hole in the middle of the frame, presumably so they can travel to the other side more easily.
