Bombus sitkensis
Sitka bumble bee, Sitka bumblebee
Bombus sitkensis, the Sitka bumble bee, is a medium-sized bumble bee species native to western North America. It is distinguished by its distinctive color pattern featuring yellow and black on the thorax with a black central patch, yellow on the first two abdominal segments, black on segments three and four with yellow posterior rims, and brownish-red terminal segments. The species exhibits an exceptionally long flight period for queens, spanning nearly the entire year in some populations. It has experienced mild population declines in parts of California due to competition with Bombus vosnesenskii for nesting sites.
