Name Used in Concept Reference: Bombus (Pyrobombus) perplexus
Taxonomic Comments: Subgenus: Pyrobombus.

Although regarded as a separate species (but see Williams, 1991) on the basis of DNA-sequence data, Hines et al. (2006) and Cameron et al. (2007) have questioned whether B. perplexus might be conspecific with B. hypnorum (Williams, 2008).

NatureServe Status

Global Status: G5
Global Status Last Reviewed: 06Oct2009
Global Status Last Changed: 06Oct2009
Rounded Global Status: G5 - Secure
Reasons: This is apparently still a very common far northern bumblebee that extends much farther south in the eastern part of its range than westward where it is basically Canadian. It has a large range, much of it in sparsely inhabited boreal regions. No evidence was found for any decline even near the edges of its range where it was historically, and still is, mostly uncommon to rare. Notably the remarkably southern Maryland collection was in 2008. Most other members of this subgenus are also either stable or increasing in abundance.

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Grixti et al. (2008), Colla and Packer (2008), and Williams et al. (2009) find this species to be relatively stable and there are apparently no reports of it being otherwise.

Long-term Trend: Decline of <30% to increase of 25%
