Their larvae like lots of oxygen and are not tolerant of warmer waters or pollution. Adult BFs live for about three weeks, laying 150 to 500 eggs either individually on the water’s surface or in clumps. Like other biting flies, males are blameless nectar feeders. Females may also consume nectar, but they need that all-important blood meal in order to reproduce.https://uwm.edu/field-station/wp-content/uploads/sites/380/2016/12/black-fly-larva.jpg
