Black flies are small, biting insects that can be a major nuisance. Black flies are small insects, typically measuring between 1/16 and 1/3 of an inch, known for their painful bites and persistent presence, understanding their characteristics is crucial for effective management and prevention. These pests are also referred to as buffalo gnats, turkey gnats, no-see-ums, sand flies, and punkies, depending on the region. Despite the various names, all black flies share a distinctive physical feature: a shiny, hump-like structure located right behind their heads.

• Physical Characteristics:
  • Size: Typically 1/16 to 1/3 inch in length.
  • Color: Dark, almost black appearance.
  • Hump: A distinctive, buffalo-like hump behind their heads.
• Habitat:
  • Larval Stage: Develops in clean, fast-moving water such as streams and rivers.
  • Adult Stage: Found near breeding sites, often in vegetation and areas with high humidity.

The black fly life cycle involves four distinct stages: egg, larva, pupa, and adult. Understanding this life cycle is essential for effective control measures. Adult black flies typically emerge in mid-spring, having overwintered as eggs or larvae in the water.

• Egg Stage:
  • Laying: Female black flies lay up to 800 eggs at a time in clean, flowing water.
  • Location: Eggs are laid on or just below the water’s surface on aquatic plants and rocks.
  • Overwintering: Eggs can overwinter, remaining dormant until conditions are favorable.
• Larval Stage:
  • Hatching: Eggs hatch into larvae, which attach themselves to rocks or vegetation in the stream.
  • Development: Larvae feed on organic matter in the water and grow through several instars (stages between molts).
  • Duration: The larval stage can last from 10 days to several weeks, depending on the species and water temperature.
• Pupal Stage:
  • Transformation: After the larval stage, black flies transform into pupae.
  • Attachment: Pupae remain attached to underwater surfaces, similar to larvae.
  • Duration: The pupal stage is relatively short, lasting only a few days.
• Adult Stage:
  • Emergence: Adult black flies emerge from the pupal stage and fly away from the water.
  • Mating: Adults mate near the water where their larvae developed.
  • Feeding: Female black flies need a blood meal to lay their eggs. They seek out animals, including birds, pets, and humans, for blood.
  • Lifespan: Adult black flies can live from two weeks to nearly three months.

Several factors influence the black fly life cycle, including water temperature, flow rate, and availability of food.

• Water Temperature: Warmer water temperatures can accelerate the development of black flies.
