Frigid bumblebee
The frigid bumblebee (''Bombus frigidus'') is a rare species of bumblebee largely found in Canada and parts of the U.S.
It is one of only two known species of bees that shows kin recognition at a level needed to prevent incestuous mating. These bees have adapted to their cold environment by being able to keep their internal temperature at a certain range while also being able to expel heat to keep the colony warm. An additional adaptation to the cold is their reduced length of copulation.
== Taxonomy and phylogeny ==
''Bombus frigidus'' was discovered in 1854 by Frederick Smith and was catalogued in ''Catalogue of hymenopterous insects in the collection of the British Museum,'' which was published in 1859. Some species from the Appalachians have been included with this species in the past, but not in newer sources. This bee should not be confused with ''Bombus mixtus'' and ''Bombus balteatus''. Bees in the family Apidae consist of honey bees, bumblebees, and stingless bees.〔
