Faits rapides

Family: Ixodidae. Genus: Haemaphysalis. Hard tick.

Identification

A hard tick in the genus Haemaphysalis. Species confirmation requires examination of diagnostic morphology; photographs, host and location alone may be insufficient.

Similar species can overlap in appearance. Confirm using authoritative keys and expert examination when identification affects health, veterinary care or surveillance.

Photographs alone cannot always confirm this species. Geographic location and host are supporting context, not conclusive identification.

Différences sexuelles et d'apparence

Adult females have a smaller scutum that permits expansion during feeding; adult males generally have a scutum covering most of the dorsum. Species-specific differences require expert review.

Hard-tick life cycle with egg, larva, nymph and adult stages. Host use and number of hosts vary by species.

Étapes de la vie

  • Egg
  • Larva
  • Nymph
  • Adult

Activité saisonnière
