Genus species: Bombus polaris

Series: Beneficial Insect Definitives (Canada 2007-2014)
As warm weather approaches, Canadians are accustomed to seeing bumblebees busily helping to pollinate their gardens. But less familiar is the northern bumblebee (Bombus polaris), as portrayed on the 5¢ stamp with a bountiful head of clover (Trifolium pratense). This docile bumblebee that thrives in the Arctic survives in below-freezing temperatures by shivering its flight muscles to generate heat. A number of Arctic flowers are almost entirely reliant on this large species for pollination.
