What a beautiful sight...a yellow-faced bumble bee, a queen, foraging on yellow bush lupine blossoms at Bodega Bay.
She buzzed from blossom to blossom at Doran Regional Park while packing a ball of red pollen that seemed to increase in brilliance with every floral visit.
A native bee, Bombus vosnesenskii, on a native plant, Lupinus arboreus.
B. vosnesenskii queens are larger than the workers. Queens measure between between 18 and 21 mm long, while the workers (females) range from 8 and 17 mm. The males? 10 to 15 mm long.
The yellow bush lupine, which can reach a height of seven feet and a width of four feet, seems to...
