Question ? Do "bumblebees" mean different things in different areas ?
around here bumblebees are the fat Bees that spend most of their time
on Dandelions, some of which get so fat & loaded down,
they end up walking home instead of Flying
(usually at Dusk, I would see one overloaded & walking home), & the only way I have ever been stung
by Bumble bees have been by stepping on them in bare feet as a kid.
I was always under the impression they would not chase a person even if their queen depended on it. if they have a queen.
No idea what their nest is like, can't say I ever saw a bumblebee nest, Will Google that next
