Abstract
Distribution of Bombus wurflenii Radoszkowski, 1859 (Hymenoptera, Apidae) in the Sudetes Around 30 species of bumblebees (Bombus Latr.) have been recorded in Poland, some of them of limited distribution. Bombus wurflenii Radoszkowski, 1859 (Phots 1, 2, 6) occurs only in the mountains and resembles the red-tailed bumblebee B. lapidarius (Phots 3, 4, 5). The paper presents historic and new localities of B. wurflenii in the Sudetes (Fig. 1). A total of 387 individuals of the species were recorded during monitoring in 2014–2016 (Tables 1, 2, 3). The bumblebee is a polylectic species; it visited 26 plant species. The most frequently visited plants were lupin Lupinus polyphyllus, thistle Cirsium palustre and aconite Aconitum plicatum (Table 4). Maintenance of mountain habitats in attractive stages of secondary succession, i.e. with the adequate number of food plants, seems to be a prerequisite to the existence of Bombus wurflenii.
