help Bombus lucorum FAQ
How can Bombus lucorum be distinguished from the buff-tailed bumblebee?
Workers typically show a lemon-yellow collar, a second yellow band, and a clean white tail, while Bombus terrestris often appears buffier. Visual identification can still be unreliable because members of the Bombus lucorum species complex closely resemble one another.
What is the Bombus lucorum complex?
Bombus lucorum is grouped with cryptic relatives such as B. cryptarum and B. magnus, whose workers can be extremely difficult to separate in the field. Researchers often use male genitalia, queen characteristics, or DNA methods for confident identification.
Where does the white-tailed bumblebee nest?
Bombus lucorum commonly nests underground in abandoned rodent burrows, though it can use other sheltered cavities. A colony is founded by a queen emerging from hibernation in spring.
Which flowers does Bombus lucorum visit?
It forages on a broad range of plants, including clovers, thistles, brambles, and garden flowers. Its relatively short tongue makes open or shallow flowers particularly accessible, although workers sometimes obtain nectar by biting through deeper corollas.
