Bombus natvigi

Richards, 1931

High Arctic Bumble Bee

Bombus natvigi is a cuckoo to the Nearctic Arctic, recognized as a distinct from Bombus hyperboreus in 2015 based on genetic analysis. It is a that invades colonies of Bombus polaris, using to manipulate into rearing its offspring. The species is currently listed as Data Deficient by the IUCN Red List, reflecting limited knowledge of its status and . Its taxonomic status remains debated, with some subsequent studies treating it as a of B. hyperboreus.
