Field Notes
Description:
This black bee has a yellow face, thorax and stripe near end of abdomen. "Head, space between mid-point of attachment of mandible and very bottom of eye compared to width of base of mandible SHORT - Very hard to tell apart from B. caliginosus, which has a very limited distribution only in the coastal regions from northern Washington to southern California, and if the specimen is found outside of this range it is most likely B. vosnesenskii" - DiscoverLife.org
Habitat:
Enjoying Perez's Sea Lavender in the backyard. It later was on Carolina Jasmine.
Notes:
GUIDE TO THE BOMBUS OF SAN FRANCISCO By Quinn S. McFrederick - "B. caliginosus is shaggier than B. vosnesenskii and has yellow hairs on the underside of the abdomen where B. vosnesenskii has only black hairs on the underside of the abdomen."
