Sarx=flesh. Phagein=to eat. Flesh flies like this one resting on a sunflower stalk help out with sanitation by laying their eggs (or in some cases live larvae) on dead animals. As is familiar to most, the maggots will consume a dead rodent in a few days, leaving nothing much but unfortunately more flies. This one is of a species in the sarcophaga genus of the flesh fly family, Sarcophagidae.
