About Bombus rupestris (Fabricius, 1793)
This species is commonly known as Bombus rupestris, first described by Fabricius in 1793. Females of this bumblebee are significantly larger than males, with a body length ranging from 20–25 mm (0.79–0.98 in), while male drones typically reach a maximum body length of only 16 mm (0.63 in). The entire body of the bumblebee is black, with orange-red coloration on the final abdominal segments. Because this species follows a parasitic lifestyle, it does not produce any worker individuals.
