    >Queen bumblebees have a newfound excuse for slacking on foraging nectar: Their tongues are holding them back.

    >Bumblebees have long, hairy tongues that help them lap up nectar from flowers. But queen bumblebee’s tongues are [less efficient at collecting nectar than those of worker bees](https://www.pnas.org/doi/full/10.1073/pnas.2527391123), researchers report January 12 in *Proceedings of the National Academy of Sciences*.

    >In the spring, when a queen bumblebee first [emerges from her winter slumber](https://www.sciencenews.org/article/hibernating-bumblebee-queen-underwater), she initially fuels herself by guzzling nectar from flowers. But once she establishes a nest and her eggs hatch into worker bees, she delegates foraging duties to the workers.

    >Those workers may be better suited to the task, according to a close investigation of the tongues of buff-tailed bumblebees (*Bombus terrestris*). The bees’ tongues range in length from around 4 millimeters to 10 millimeters. The queens, who are bigger than the workers, tended to have longer tongues. But those longer tongues had relatively less hair, scanning electron microscope imagery revealed.

    Neat reminder that even within the same species, evolution fine tunes roles so differently that what seems like a downgrade is really just specialization 🙂

    I just realized i always assumed bumble bees mated in pairs. Off to wikipedia i go

  4. That makes sense. Human queens are less suited to construction work, since their arms have less strength and their hands have less calluses on them.
