Unlike ticks from other genera, [8] deer ticks do not have eyes. [3] [8] The scutum is dark, inornate (plain), and, in unfed females, contrasts with the exposed orange or red remainder of the idiosoma. [3] There are no festoons. [3] [9] Ixodes ticks have an anal groove that resembles a horseshoe [9] on their underside anterior to the anal pore.
Tick-borne relapsing fever is transmitted through the bites of lice or soft-bodied ticks (genus Ornithodoros). [10] Each species of Borrelia is typically associated with a single tick species, with Borrelia duttoni being transmitted by O. moubata , and being responsible for the relapsing fever found in central, eastern, and southern Africa.
The Ixodidae are the family of hard ticks or scale ticks, [1] one of the three families of ticks, consisting of over 700 species. They are known as 'hard ticks' because they have a scutum or hard shield, which the other major family of ticks, the 'soft ticks' ( Argasidae ), lack.

A habitat preferred by ticks is the interface where a lawn meets the forest, [67] or more generally, the ecotone, which is unmaintained transitional edge habitat between woodlands and open areas. Therefore, one tick management strategy is to remove leaf litter, brush, and weeds at the edge of the woods. [ 68 ]
Rhipicephalus is a genus of ticks in the family Ixodidae, the hard ticks, consisting of about 74 or 75 species. [2] [3] Most are native to tropical Africa. [2] Rhipicephalus ticks are commonly called 'the brown tick' as they are mostly brown in colour. [4] Most adult ticks in this genus do not have colour patterns on their scutum (inornate). [4]
Ixodes ricinus, the castor bean tick, is a chiefly European species of hard-bodied tick.It may reach a length of 11 mm (0.43 in) when engorged with a blood meal, and can transmit both bacterial and viral pathogens such as the causative agents of Lyme disease and tick-borne encephalitis.
Daily searching usually gives a person a few days to find an attached tick. However ticks at the early stage of attachment are small and flat and so easily missed. Whilst most ticks on dogs are found around the head, neck and shoulders, they can be anywhere on the dog's surface. They are easily missed on the face, legs and between the toes.
