The Acari are a subclass of Arachnida and comprise the mites and ticks. They represent one of the most ancient lineages of terrestrial life, and have colonised almost every habitat on the planet and occupy a huge range of ecological niches. This recording scheme has been established to gather and collate biological records on UK mites (orders Mesostigmata, Sarcoptiformes and Trombidiformes) from all habitats. Ticks (order Ixodida) have their own separate recording scheme.
