Bumblebees are important pollinators of crops and wildflowers in northern temperate regions. The number of bumblebee species has declined in recent decades, particularly, in developing regions. Here, we investigated the distribution and floral preferences of founder bumblebee queens that were collected between 2000 and 2012 in Korea with the intention of gathering information useful in the conservation of native bumblebee populations. A total of 13,130 overwintered bumblebee queens were collected at 63 locations from 8 provinces; the collected bumblebees consisted of five species of native bumblebees (Bombus ardens, B. ignitus, B. hypocrita spporoensis, B. ussurensis and B. consobrinus wittenburgi) and one species of exotic bumblebee (B. terrestris). The dominant species were Bombus ardens Smith and Bombus ignitus Smith, which accounted for 7,462 (56.8%) and 3,725 (28.4%) of the collected bumblebees, respectively. As a proportional distribution of the founder bumblebee queens that were collected, B. ignitus was the most common (9.8%-78.5%), followed by B. ardens (9.8%-66.1%), B. hypocrita spporoensis (0.9%-31.4%), B. ussurensis (0.8%-22.2%), B. consobrinus wittenburgi (0.1%-3.8%) and B. terrestris (0.0%-1.1%). The bumblebee queens foraged from 7 families of plants and 18 plant species. B. ignitus bumblebees were primarily collected from Prunus serrulata Matsumura and Corydalis speciosa Max, and B. ardens bumblebees were primarily collected from Rhodldendron mucronulatum Turcz and Prunus yedoensis.
