Western bumblebee
The western bumblebee is a fuzzy black and yellow bee from western North America. Some have a white tip on their tail, and some have a reddish-brown stripe. It lives in a big family led by one queen, in a nest under the ground.

How fast is it?
Fun facts
The queen starts the nest alone in spring, often in an old hole left by a mouse or another small animal.
A nest can have up to about 1,600 worker bees.
Only the young queens survive the winter. Next spring each one starts a brand new family.
It became much rarer in some places, but scientists have seen signs that it may be coming back.
