Bombus cryptarum is a species of bumblebee. It is native to the northern hemisphere, where it is "one of the most widespread bumblebees in the world." It occurs throughout Europe, Asia, and western North America. It is known commonly as the cryptic bumblebee.
The complete distribution of the species is unclear due to taxonomic uncertainties. It is part of a species complex of several bees in the subgenus Bombus sensu stricto, which are very similar and difficult to tell apart.
It has only recently been identified in the British Isles. Bombus cryptarum differs from Bombus magnus phylogenetically and in labial gland secretions. Bombus cryptarum florilegus, an endangered subspecies in Japan, had previously been identified as having a close relationship with Bombus lucorum. Bombus cryptarum florilegus was found to have low genetic diversity in Japan and maintained their own population with immigration from Notsuke Peninsula to the Chishima (Kuril) Islands
In northern areas this bee lives on plains, especially in heather ecosystems. In southern regions it can be found in mountain habitat. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cryptic Bumble Bee is recorded against all the insects logged in Banff National Park (16 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
