Thomson, 2001).The genus Bombus includes 250 bumble bee species worldwide, with 46 species present in North America, north of Mexico (Williams et al., 2014). The species utilizes bundles of hay or long grass to create sheltered nests above ground. Peter Soroye, one of the study's authors, tweeted about the research, saying "in 25 years, the likelihood of finding a bee species declined on average by 46% in North America & 17% in Europe." The new study analyzed more than half a million bumblebee observations of 66 species in Europe and North America from two time periods; 1901 to 1974 and 2000 to 2014.

At least APHIS forbids importation of bees from other nations except Canada, but between 1992 and 1994 it permitted western and eastern bumble bee queens to be shipped to Europe for rearing and their colonies to be distributed throughout North America. The hornets kill and dismember the bees, returning to their nest with the bee thoraxes, which they feed to their larvae, leaving heads and limbs behind. [15], Current research states that Bombus pensylvanicus is uncommon and most likely declining. Peter Soroye, one of the study's authors, tweeted about the research, saying "in 25 years, the likelihood of finding a bee species declined on average by 46% in North America & 17% in Europe."
