Bombus pensylvanicus, the American bumblebee, is a threatened species of bumblebee native to North America. It occurs in eastern Canada, throughout much of the Eastern United States, and much of Mexico.[1]
Once the most prevalent bumblebee in the southern United States, populations of Bombus pensylvanicus have decreased significantly in recent years,[3] including in its scientific namesake state of Pennsylvania, where its numbers are considered critically low.[4] Overall the population has dropped nearly 90% in just the last 20 years.[5]
Bombus pensylvanicus tends to live and nest in open farmland and fields. It feeds on several food plants, favoring sunflowers and clovers,[6] and functions as a pollinator.
