I'm new to beekeeping and have checked the hive about 3-4 times now. I filled up the bottom box and added another on top minus 2 frames to allow room for sugar water. This last time I tried to check on things, the bees were quiet at first but really charged out in a big uproar as soon as I added smoke (haven't they read the literature?). I puffed more smoke and they got madder and started stinging. I decided discretion was the better choice so I quickly got out of the area.
Lately, I've noticed some other bees at the entrance that seem different. One (on left side of image) is probably a drone? but the other (right side) is about the same size but just a much lighter color than the rest. I haven't seen either of these for the past week or so, so it might be moot, but I wondered what the situation might be. Any help/insight?
