Composition of two cropped images

A hovering fly (or syrphid flies, family Syrphidae) on an ipomea (morning glory) flower. The color of these flies resembles that of bees and wasps, scaring off potential predators (Batesian mimicry). Adult flies feed mainly on nectar and pollen and are important pollinators. In the first photo, the fly hovered over the flower for several seconds, "froze" in place, and let me photograph it in the air. Then she sank into a flower and began her meal.
