Bees have a small wing size to body ratio. In fact, a common myth based on this information states that bees should not be able to fly. The truth is... they need to work harder than most insects in order to fly... they are bees after all! Work is their thing! To compensate they flap their wings a shorter span (90 degrees instead of 165) and more times per second (about 240 versus 200).
I drew this big bottomed lady from a photo taken in my garden during the summer. I'm exploring images for a body of larger watercolor paintings and the bees are, yet again, my muse.
