Abstract Critical revision of the terms “pasture (non-nidicole) type of parasitism” and “nest-and-burrow (nidicole) type of parasitism” widespread in the literature forces us to abandon these terms. All the hard ticks are characterized by the same type of parasitism: they belong to a group of temporary ectoparasites with prolonged feeding (Balashov, 2009). By the type of habitat of non-parasitic life stages these parasites can be subdivided into ecological groups of nidobionts (dwellers of nests and burrows) and nemobionts (comprising ticks dwelling outside nests and burrows at non-parasitic life stages).
