Bombus erzurumensis

Bombus erzurumensis is a species of bumblebee found in Turkey (north-eastern Anatolia) and northern Iran.

Description
The thorax is whitish with a black band between the wings. The two first terga (abdominal segments) are white, followed by a black band; the rest of the abdomen is red. Variation in the pattern is considerable, but the form B. erzurumensis f. oezbeki (earlier considered a separate species, B. oezbeki) has white fur on the face and the corbiculae (pollen basket) is covered with red hairs.

Ecology
Bombus erzurumensis is a mountain species, living on alpine steppes between 1550 and 3000 m above sea level. It collects nectar and pollen from flowering plants, for example, Cephalaria, Campanula, Jurinea, and Nepeta species.
