What habitat structure is frequently associated with B. fervidus observations in New York State and Vermont?
Answer
Open, shrubby, or transitional habitats bordering wooded areas.
In established observation areas like New York State and Vermont, records show that Bombus fervidus prefers habitats that are not densely forested. The preference leans toward open areas, shrubby borders, or transitional zones. This structure is ecologically sensible because it provides the necessary sunlight for thermoregulation, which is vital for active foraging females, and ensures clear access to flowers, which supports both the parasite's energy needs and the necessary floral resources required by the host queen when establishing her initial nest.
