About all I do know about them is that bumble bees are becoming endangered in many areas. They're somewhat more friendly than a lot of other flying stinging insects, preferring to visit flowers and be on their way. :)

I did a bumble bee video here. But shame on DTube for not playing videos after the first few weeks :(
