Because they have compound eyes, that is, formed by about 4000 facets – called ommatidia – each. They give the fly a nearly 360-degree view. In addition, insects in general have a large number of sensory structures spread throughout the body. “These sensors allow the fly to feel minimal changes in the environment, be they chemical, hydration, temperature or pressure”, says biologist Pedro Gnaspini, from the University of São Paulo. “That’s how it identifies any movement of air around your body,” he says. Due to the small size of the insect, it is also obvious that a gust of air that would not be noticed by a human seems like a gale to the fly, causing it to flee. The speed of flight is guaranteed by membranous wings, with very powerful muscles, which give them quick movements and precise maneuvers at the slightest sign of danger.

Hypersensitivity and ultra-rapidity The insect’s two greatest talents lie throughout its body.
Membrane wings make the fly’s flight especially swift.
Sensors throughout the body pinpoint minute changes in ambient temperature and pressure
