Concept Reference Code: A12WIL02EHUS
Name Used in Concept Reference: Bombus (Bombus) cryptarum
Taxonomic Comments: Subgenus: Bombus.

The taxonomy of this subgenus has long been unstable. It had been particularly unclear whether any North American populations really belonged in the species B. lucorum. Williams et al. (2012), based on multicontinental genetic studies of this subgenus, concluded that much of what had been called B. lucorum, including all North American populations, is actually conspecific with Bombus (Bombus) cryptarum, which ranges across much of Europe and Asia into western North America. All North American records for B. lucorum or B. moderatus are transferred to this species. B. moderatus becomes a synonym of B. cryptarum.

NatureServe Status

Global Status: G5
Global Status Last Reviewed: 14Jun2017
Global Status Last Changed: 24Aug2012
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G5 - Secure
Reasons: This is one of the most widespread bumblebees in the world. It is common in much of its range, including the North American portion. It is not known to be declining seriously in places where habitats remain. North American populations should be monitored considering the severity of declines of other species in the same subgenus.

IUCN Red List Category: DD - Data deficient

NatureServe Global Conservation Status Factors

Range Extent: >2,500,000 square km (greater than 1,000,000 square miles)
Range Extent Comments: According to Williams et al. (21012) B.(B.) cryptarum is the most widespread species of the subgenus and extends across much of Europe into Central Asia, north China, the Kuril Islands, the east coast of Russia, and north-western North America. In North America this species occurs in Alaska and western Canada southeast to about Banff.

Number of Occurrences: > 300

Overall Threat Impact Comments: Koch (2011) did find a strain of Nosema in this species (as B. moderatus) in Alaska. This may well be a long-term native parasite in that area. This situation should be monitored, but for now there does not appear to be cause for concern.
