Acariformes

Acariformes are a subclass of mites that are known for their small size and diverse habitats. They are one of the two main groups of mites, the other being the Parasitiformes. Acariformes are also known as Actinotrichida, which refers to their "rayed hairs".

Characteristics

Acariformes are typically very small, with most species measuring less than 1 mm in length. They have a simple body structure, with a fused cephalothorax and abdomen. The body is covered in fine, hair-like setae.

The Acariformes have a unique respiratory system, with spiracles located on the sides of the body. They also have a unique digestive system, with a foregut that is lined with cuticle, a midgut that is not lined with cuticle, and a hindgut that is again lined with cuticle.

Classification

The Acariformes are divided into two superorders: the Sarcoptiformes and the Trombidiformes. The Sarcoptiformes are further divided into two orders: the Oribatida and the Astigmata. The Trombidiformes are also divided into two orders: the Prostigmata and the Sphaerolichida.

Ecology and behavior

Acariformes are found in a wide range of habitats, from soil and leaf litter to the fur and feathers of animals. Some species are parasitic, while others are free-living. They feed on a variety of materials, including plant matter, fungi, and other small organisms.

Human interaction

Some species of Acariformes are of economic importance, as they can cause damage to crops and stored food. Others are beneficial, as they help to break down organic matter in the soil.
