This is considered the most serious external parasites of Australian cattle, though they also affect cattle accross the southern hemisphere and the southern states of the USA. It is able to complete its life cycle in just 2 months under optimal conditions and lay 2000 - 3000 eggs during this time. It is important in its ability to act as a vector for ''Babesia bigemina'', ''Borrelia theileri'' in South America and in Australia of ''Coxialla burnetti'' and ''Anaplasma marginale''. These organisms can be passed down for up to 5 generations of ticks regardless of the hosts on which they feed as they can be passed transovarially between generations.

The entire life cycle of this tick is spent on a single host and can be completed in just 6 weeks. It is an important species as it is a vector for ''Babesia bigemina'' and ''Babesia bovis'' that are responsible for texas cattle fever. As well as its ability to transmit ''Anaplasma marginale'' like many other tropical hard ticks.
