Bumblebees

Bumblebees are community insects that are characterized by black and yellow body hairs, habitually in bands. However, some species have orange or red on their bodies, or may be completely black. Another noticeable characteristic is the soft nature of that hair, called pile, that covers their entire body, making them appear and feel furry. They are best illustrious from similarly large, fuzzy bees by the form of the female hind leg, which is modified to form a corbicula; a shiny dipped surface that is bare, but surrounded by a fringe of hairs used to transport pollen.

Bumblebees are normally found in higher latitudes and/or high altitudes, though exceptions exist. A few species range into very cold climates where other bees strength not be found; B. polaris can be found in northern Ellesmere Island - the northernmost occurrence of any eusocial insect - along with its parasite, B. hyperboreus. One reason for this is that bumblebees can regulate their body warmth, via solar emission, internal mechanisms of "shivering" and radiative cooling from the abdomen. Other bees have similar physiology, but it has been best studied in bumblebees.
