Bombus flavidus appalachiensis
A subspecies of the cuckoo bumble bee Bombus flavidus endemic to eastern North America, ranging from the Appalachian Mountains to the eastern boreal regions of the United States and far southeastern Canada. Described in 2021 following integrative taxonomic analysis that revealed this population as genetically and morphologically distinct from western North American and Palearctic populations. As a social parasite, this subspecies does not construct colonies or collect pollen but invades nests of other bumble bee species.
