Proturans are tiny whitish colored hexapods that live in moist soil or humus, in leaf mold, under bark, and in rotting logs. They feed on fungal spores and rotting organic matter. These unusual organisms develop by anamorphosis, a process in which segments are added posteriorly during development.

They can be recognized by their minute size, 0.6 to 1.5 mm in length; their somewhat conical head; lack of both eyes and antennae; exposed mouthparts; 12 segmented abdomen; one segmented tarsi; styli present on first three abdominal segments; and lack of cerci. There are only 3 families of this order in North America and only 4 families worldwide.
