Hello beekeepers, I am a new beekeeper this year and I have a hive (carnolians) that seems to be thriving. Then, a couple weeks ago I captured a swarm in a nearby town when it landed in a coworker's yard. The new colony seemed to do fine for the first couple weeks and were drawing comb and the queen was laying (I didn't find her until a week later, but she was there). On July 1st, while inspecting the new hive, I noticed some of the bees seemed to be falling from the frames, but I didn't think much of it (inexperience). Then, suddenly on July 5th, almost the entire hive died within about 12 hours. In the morning, there were a dozen dead bees in front of the entrance, and by evening it was literally clogged with dead bees. All around the hive on the ground were bees stumbling, jittery and struggling to fly. Inside, larvae were dropping from the frames. I looked at these bees up close (insides also to check for nosema) and don't see anything physically wrong with them, and no signs of fouled brood cells. Below is a link to a few dozen pictures I took on the 5th. Does anybody know what could cause this? Like I mentioned, my other hive, which is about 15 yards away, seems perfectly fine. After the 5th, there were maybe 100 bees left, including the queen, but they still can't fly. The larvae appear to be starving in their cells. Also I should mention, all the equipment (deep and frames) for this hive was brand new. Link to photo album Has anybody seen this happen before?
