  • Also called the harvest mite
  • Not host-specific
    • Will parasitise any animal, including humans
  • Only the larval stage is parasitic
    • Nymphal and adult stages are free-living in the soil
  • Mite numbers are highest in late summer in temperate climates
    • Mite numbers are constant all year in tropical regions


Recognition

  • Six legs
  • Bright orange in colour
  • Hairy
  • No spiracles
    • Breath through cuticle


Pathogenesis

  • Larvae insert mouthparts into skin and inject cytolytic enzymes
  • Feed on partly digested host tissue
  • Causes irritation
  • Can cause a hypersensitivity reaction
  • Mites found on head, ears and flanks of pets
  • Mites found on face and limbs of grazing animals (depending upon host height)
