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

Bombus flavidus

The current, accepted scientific nomenclature for the insect commonly known as the Yellowish Cuckoo Bumblebee is *Bombus flavidus*. This binomial name, established through modern scientific scrutiny often involving genetic or morphological data, is used in current field reporting and conservation tracking efforts, such as those managed by NatureServe. This stands in contrast to its former designation, *Bombus fernaldi*, which is now considered a historical synonym or older reference point. The use of *B. flavidus* ensures consistency when correlating past observations with contemporary ecological modeling across different regions, like comparing data between Idaho databases and Vermont monitoring projects. This precision is crucial for understanding the species' true distribution and health.
