Quick facts

Family: Ixodidae. Genus: Amblyomma. Hard tick.

Identification

A hard tick in the genus Amblyomma. 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.

Sex and appearance differences

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.

Life cycle

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

Life stages

  • Egg
  • Larva
  • Nymph
  • Adult

Seasonal activity

Seasonal activity is not generalised without accepted location-specific evidence.

Distribution

Detailed distribution is shown only when supported by governed country or region occurrence records.

Presence, established populations, habitat suitability and disease risk are distinct evidence categories.

Prevention and removal guidance

Use current public-health and veterinary guidance, avoid known tick habitats where practical, use suitable repellents or protective clothing, and check people and animals after exposure.

Remove attached ticks promptly using fine-tipped tweezers or an appropriate tick-removal tool. Seek medical or veterinary advice when symptoms or concerns arise.
