Bombus wurflenii is a species of bumblebee found in several parts of central and northern Europe to Turkey and the Crimea peninsula in the southeast.

Description

This bumblebee has a very short proboscis (tongue), powerful, toothed mandibles, and a short head. The queen has a body length of Шаблон:Convert, a wing span of Шаблон:Convert and a black, shaggy fur with the three last terga (abdominal segments). The workers, which have body lengths ranging from Шаблон:Convert and wing spans from Шаблон:Convert, look like the queen, except for the lesser length. The males are Шаблон:Convert in length, have a wing span from Шаблон:Convert and are otherwise similar to the females. A lighter form, with most of thorax and the two anterior terga covered in pale fur exists.

Ecology

The species is mainly found in mountainous areas. In the Balkans, it is found from Шаблон:Convert above sea level, and in Turkey between Шаблон:Convert and Шаблон:Convert. The nest is small, containing 80 to 150 individuals.

The bumblebee predominantly forages on flowers such as Vaccinium, Lamiaceae, Scrophulariaceae and Fabaceae. According to Goulson, this species is an opportunistic nectar robber. The bees cut a hole into the back of the flower to access nectar, and so they do not participate in pollination.

Distribution

In Europe, it can be found in Austria, Belgium, the Czech Republic, France, Germany, Hungary, Italy, Norway, Poland, Romania, Slovakia, Slovenia, Spain, Switzerland, Scandinavia, the Ural and Caucasus in Russia, northern Turkey, and the Crimean Peninsula. It is absent from the British Isles, and its presence in Finland is disputed.
