Fur,
Are there some hives that are just meaner than others? I have caught 4 different swarms, and all 4 have been right at dark or even after dark. # of them have been very gentle and easy to work with. But the one I caught Weds. evening/night seems to be really mean. I caught most of the bees that night , and left the box there all day yesterday to get the rest of the bees. I stopped by yesterday evening, and they were working like crazy in and out of the hive. I waited until about 10:00 to go and close them to move, and they were still guarding the entrance and would come out aggressively at every noise or the light. I went back this morning at 4:00 and was able to get them closed up, moved them and set up at new home and when I opened they were ticked. They just seem super aggressive.
