Queen bumble bees reportedly establish colonies in abandoned rodent burrows. In early spring, queens searching for abandon rodent burrows as nesting sites face the challenge of locating the often small and visually obscured entrance hole to these burrows. The queens’ zig-zag borrow -searching flight pattern with an overall forward motion is reminiscent of animals tracking odor plumes and is strong indication that queens rely primarily on rodent scent to locate the entrance to burrows. We tested the hypothesis that bumblebee queens seeking nest sites in Spring sense, and behaviorally respond to, urine odorants from house mice.
