This large, colorful fly(a.k.a. Syrphid fly) would hover motionless other than the blur of its' wings. When it landed on these leaves I was able to quickly snap this picture. The larvae of these flies look a bit like strange caterpillars. Some hover flies look a lot like bees, but they don't sting. When one animal looks like another similar, but unrelated animal, it is called "mimicry". A bird, thinking this fly was a bee, would not eat it.
