Haematobia irritans - Scott Bauer Wikimedia Commons
  • Also known as the horn fly
  • Resident biting fly
    • Spends most of its time on the host along the back, shoulders and sides
  • Mainly resides on cattle
  • Feed on areas where the skin is thin e.g. dewlap, belly and udder
  • Common in southern England, the USA, Europe and Australia


Recognition

  • Similar to the stable fly
  • Smaller at 4-7mm long


Life cycle

  • Eggs laid in fresh cattle dung
  • Larvae burrow into dung and pupate
  • Life cycle takes 1 week


Pathogenesis

  • Production losses
  • Disease transmission
    • Pathogenic bacteria and viruses via mechanical transmission
    • Helminths can be introduced into the host
      • E.g. Stephanofiliaria a filarial nemadode found in the skin of cattle overseas

Control

  • Resident fly so easier to control than visiting flies as spends more time in contact with the host
