I have an extensive flower garden as I grow crops of cut flowers. In the last two weeks I have been "visited" by a giant bumblebee, who repeatedly comes out of nowhere and is suddenly just a foot or two from my face. He/she has not moved in for an attack, but appears menacing just the same! I try to remain calm and stand quietly or move slowly to a new place. Normally, in my line of work, I am around bees all the time and we co-exist quite peacefully and respectfully. But this very large bee does not give me the impression of one to be taken lightly! I have "weapons" at hand (since this happens each and every time I am cutting) but would prefer to make peace not war!
Any suggestions about just what this bee may have on its mind and how I should behave toward its sudden arrivals and buzzing about my head? What ARE these giant bumblebees which seem to be new to our area? And yes, it IS a bee.
Also we seem to have an underground bee colony in another area - right near a gateway and water hydrant that are quite necessary for me to access. I know where the nest is located and give it wide berth. It is in a line of rugosa roses which are currently being attacked by Japanese beetles. In my efforts to knock the beetles into soapy water (and being VERY careful not to disturb the bees) I have been chased down and stung TWICE by bees which I did not provoke. Why this aggression? These bees, unlike the huge one above are normal-sized bumblebees.
Insights into bee behavior and what I should do?
