I was going through one of my hives the other day and one bee was making the oddest noise. It was a higher pitch and at first I thought there might be another insect. Is that a sign of a hive that swarmed? I suspect they did. There was a lot of scouting activity a few days before I checked the hive, I couldn't find the queen and there were no eggs or young larva. Q: Is there any information on the sounds that honey bees make?
