In 2005, this species was reported from Nova Scotia, a rapid and wide increase in its distribution. In this paper, we document a similar rapid spread of A. manicatum into western North America, including British Columbia and Idaho, and discuss the potential risks of this species in eastern Canada. In addition, the potential of DNA barcoding as a rapid and reliable means of recognizing adventive bee species is advocated.1 aGibbs, Jason1 aSheffield, Cory, S.  uhttps://apoidea.myspecies.info/node/63
