What is the current scientific designation for the Yellowish Cuckoo Bumblebee?

Answer

Bombus fervidus

The current scientific name for the Yellowish Cuckoo Bumblebee is Bombus fervidus. This reflects a recent reclassification driven by ongoing taxonomic study within the Bombus genus complex. The former name, Bombus fernaldae, is still frequently encountered in older literature or field guides. It is important to distinguish these scientific names from those of the host species, such as Bombus impatiens or the rarer Bombus affinis, which are social bumblebees that serve as hosts for this parasitic species.
