Identification

A soft tick in the genus Otobius. Species confirmation generally requires specialist morphological examination.

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

External sexual differences may be subtle; expert examination may be required.

Life cycle

Soft-tick life cycle with egg, larva, one or more nymphal instars and adult stages; feeding behaviour varies by species.

Life stages

  • Egg
  • Larva
  • Nymph
  • Adult

Seasonal activity

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

Hosts

  • Humans (Homo sapiens)
  • Horses
  • Cattle (Bos taurus)

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.

Medical and veterinary relevance

A soft tick whose immature stages infest ears of animals; human encounters are reported. Species confirmation requires appropriate examination.

Recorded host relevance includes humans, horses, cattle; significance varies by place and evidence.

Vector and pathogen evidence

Vector status is stated only where the cited source distinguishes confirmed transmission from detection, laboratory competence or possible association.

Medical importance

Veterinary importance

Host and veterinary relevance are limited to the cited evidence and require local interpretation.

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.
