How Long Do Black Flies Live For?
Black flies are small insects that live in water. They emerge as adults during mid-spring and live for two to three weeks. They need blood meals to develop and lay their eggs. Females seek out animals to feed on blood. Depending on their environment, they may breed several times a year.
Black flies develop as larvae in rivers or streams. They feed on small organic materials, including algae and protozoa. They then pupate in the water, rising up to the surface of the water in a bubble of gas. They live for approximately three weeks and are not a threat to humans.
Black flies are a nuisance during the spring and summer seasons in northern areas. Most species spend the winter in the egg or larval stage. The adult stage usually appears in late spring or early summer. While most species lay eggs in running water, there are also species that lay eggs on moist surfaces.
Black flies live for two to three weeks as adults. They usually breed during spring and summer, and are found throughout the country. They are active during the day but are most active in the early evening. You should wear light-colored clothing and avoid scratching if you come in contact with black flies. Topical products can also help reduce the itchiness caused by black flies.
