Which geographical area includes documented observations showing the characteristic yellow-dominant coloring of this species?

Answer

Montana

The species exhibits a wide distribution spanning outward from the eastern parts of North America. Specific data points confirming the presence of the characteristic yellow-dominant coloring have been recorded in regions across this range. For example, observations documented in the state of Montana serve as a key piece of evidence supporting its presence in certain western areas where yellow-dominant hues are observed, distinguishing it from more consistently striped bumblebees found in many adjacent ecosystems.
