What are duck fleas called? - in detail
The flea that parasitizes ducks is the waterfowl flea, scientifically known as Ceropsylla sp.. It belongs to the family Ceratophyllidae and is specialized for aquatic birds. Adult fleas are small, dark‑brown, and laterally flattened, allowing movement through dense plumage and water‑logged feathers.
Key characteristics:
- Host range: Primarily mallards (Anas platyrhynchos), teal, and other dabbling ducks; occasional infestations on geese and swans.
- Life cycle: Eggs are laid on the host’s feathers; larvae drop into the nest litter or water, where they feed on organic debris and adult flea feces; pupation occurs in a silken cocoon within the nest material; emergence aligns with the host’s breeding season.
- Distribution: Found in temperate and sub‑tropical regions of North America, Europe, and parts of Asia where waterfowl breed and nest near freshwater habitats.
- Impact on hosts: Heavy infestations cause feather damage, reduced insulation, and irritation; severe cases may lead to anemia or secondary infections.
Control measures focus on nest sanitation, removal of debris, and treatment of breeding birds with approved insecticidal preparations. Monitoring programs track prevalence by inspecting nests during the early breeding period and counting adult fleas on captured birds.
