Acariformes

Acariformes (pronounced: a-car-i-form-es) is a subclass of Arachnida that includes the majority of mites and ticks. The term "Acariformes" is derived from the Greek words "akari" meaning mite and "formes" meaning shape or form.

Etymology

The term "Acariformes" is derived from the Greek words "akari" meaning mite and "formes" meaning shape or form. This term was first used in the early 20th century to classify a group of mites and ticks that share similar characteristics.

Classification

Acariformes is a subclass within the class Arachnida. It is further divided into two superorders: Trombidiformes and Sarcoptiformes. These superorders contain several families of mites and ticks, including the well-known Dermatophagoides (house dust mites) and Sarcoptes scabiei (the itch mite).

Characteristics

Acariformes are small arachnids, typically less than 1 mm in length. They have a simple body structure with a fused cephalothorax and abdomen. Most species have four pairs of legs, although some species may have fewer. Acariformes are known for their diverse habitats and lifestyles, ranging from free-living species in soil and water to parasitic species on plants and animals.
