The apiariulus and I were inspecting the hives, and we noticed a brouhaha in the front of the Valentinium. The Valentinium is the hive whose mouseguard I removed last month, as the entrance had seemed too constricted for its large population. Today we saw lots of bees flying in, many of which were being blocked by guard bees. We saw bundles of bees fighting it out near the entrance. We saw dead bees being flung from the hive. However, I smelt no alarm pheromones, which is to say, I detected no whiff of bananas. Nevertheless, I plugged two thirds of the entrance with grass, and this seemed to calm things somewhat.
I went out a couple of hours later, and things seemed calm, but I left the grass in.
