Bb is a Bumblebee. Bumblebees are large, fuzzy insects with short, stubby wings. They are larger than honeybees, but they don't produce as much honey. However, they are very important pollinators. Without them, food wouldn't grow. 

Conservation status

Many bumblebees are listed as endangered, vulnerable or near threatened by the International Union for Conservation of Nature and Natural Resource's Red List of Threatened Species.

Bumblebees don't die when they sting. This is trait found in honey bees.
