Long-tongued bumble bee queens of Bombus balteatus visit flowers of the alpine skypilot Polemonium viscosum. These large bees have a distinctive flight buzz, the bee version of a cargo-plane flying from flower to flower. Photo courtesy of Zoe Moffett, Colorado College
Bombus balteatus queen collecting nectar from the alpine clover, Trifolium parryi. The buzzes of bees flying from flower to flower tell scientists how much pollination the clover population is getting over time and predict seed production in these alpine wildflowers.
