| The harmonic radar has been used before to track the flights of bumblebees and honeybees. |
| Enclosing bumblebees permits us to control the pollen parent, as well as the female parent. |
| There were just tons of bumblebees out there this spring, when the honeybees were in the hives because it was too cold. |
| Both species bloom during mid summer to early fall, and are pollinated by either hummingbirds or bumblebees. |
| Honeybees, bumblebees, various flies and beetles, and the hummingbird clearwing frequent milkweeds too. |
| Along with my collaborators, I have experimentally investigated that cost in bumblebees. |
