Honey bee sperm has a very long tail, about 225 micrometres (µm) in length. It dwarfs the tails of the sperm of larger vertebrates, which are typically in the 40-75 µm range.Why these long tails? Do they aid motility – how strongly and how fast the sperm moves? Are they relevant to the sperm’s longevity in the queen’s sperm sac? Do they determine which sperm the queen decides to hold on to and which to shed?To answer these questions, we need the right technology.
