High-resolution numerical simulations of a tethered model bumblebee in forward flight are performed superimposing homogeneous isotropic turbulent fluctuations to the uniform inflow. Despite tremendous variation in turbulence intensity, between 17% and 99% with respect to the mean flow, we do not find ...
These turn out to be very interesting questions that reveal a lot of physics. Jumbo jets have fixed wings because their wing area and speed are large enough to satisfy the lift equations for flight. But the small wings on a bumble-bee are much less efficient. Coupled with low speeds and ...

Bumblebee Flight Dynamics During free flight in both steady and unsteady flows, the flight path of the bees typically consisted of large-amplitude motions at low frequencies (i.e., “casting”) that combined lateral translation and rolling (Fig. 1a)6. In unsteady flow, higher frequency translat...
Honeybee mite raises bumblebee virus risk. Credit: Sophie Hedges A mite that spreads a dangerous virus among honeybees also plays an indirect role in infecting wild bumblebees, new research shows. The Varroa destructor mite lives on honeybees and can spread deformed wing virus (DWV) throughout...
It seems clear that science has not proven that bumblebees cannot fly. This myth began after attempting to use the equations of aerodynamics, which beautifully describe the flight of manmade objects, to describe the flight of nature’s best aerialists, the insects. But when the differences betw...
Bee-pollinated plants face a dilemma in that bees both passively transport pollen grains among conspecific flowers and actively collect pollen to feed their larvae. Therefore, mechanisms that reduce pollen collection by bees have evolved in melittophilous plants. Malvaceae pollen is uncollectable for...
