I went home at lunch today and saw the dreaded swarm frenzy outside my package hive. Ugh. There are a few 20' red buds near by, but noooooo, the girls picked a branch 80' up in a poplar tree. I walked over to the hive and most bees were heading in to the hive. I walked around the huge poplar tree and could see the swarm setteling on a branch. About 15 minutes later I saw a huge bunch of bees flying around in front of the hive. I thought " oh no a second swarm. Double ugh! The frenzy in front of the hive got smaller and smaller and bees were going in to the hive. Walking around the poplar tree, the swarm on the branch was much smaller. Another 15 minutes had almost no swarm on the branch and most bees back in the hive. I have never heard of this. Anyone out there ever seen a swarm leave and then come back? Thanks for your help.
