While I was shooting some close up video of a couple of bees on a St. John's Wort blossom I noticed some interaction. When I replayed the scene on my laptop, it was more like a skirmish. One bee actually tried to bite the other one's leg. I'm wondering why some bees get along fine (there's a scene with SEVEN bees on a blossom)? Is it how related they are? Same drone 'father?' Any thoughts?
