Two characteristics that identify the California bumble bee (Bombus californicus):

  1. Hair. Like all bumble bees, this California native is VERY hairy.
  2. Color. Black face (sometimes called the black-faced bumble bee), yellow fuzz at the front of the thorax that makes it look as though it is wearing a yellow scarf, and a yellow stripe toward the bottom of the abdomen.
