These three species are the only ones with any red hair. The Tricolored Bumble Bee is one of the most common species in the state, though scarce in the Champlain Valley. Red-belted Bumble Bees are incredibly variable but often have significant red. They are uncommon to rare and largely limited to the Champlain Valley. The Rusty-patched Bumble Bee was once common in Vermont but hasn’t been found in the state since 2000 and is now federally endangered.
