Bombus ternarius
Behavior
Queen and worker bumblebees can sting. Unlike honey bee stingers, a bumblebee's stinger lacks harpoon-like barbs on the end of the stinger, so B. ternarius can sting repeatedly without risk of disemboweling itself and dying. B. ternarius is not normally aggressive, but will sting in defense of its nest or when threatened or provoked.
