A small, lightweight fly species, it flutters around with gentle wingbeats. Drawn to the scent of food or fermenting fruit, it appears easily and breeds at a rapid pace. Despite its short lifespan, it lays numerous eggs, quickly increasing its population. It can be found both inside the home and outdoors.
