Astigmata

Astigmata is a suborder of mites and ticks, collectively known as acarids, within the arachnid class Arachnida. These tiny arthropods are found globally in diverse habitats, from hot springs to high altitudes. While most mites have eight legs as adults, their larvae typically have six.12

The Astigmata suborder includes familiar types such as mange, itch, or scab mites, which can affect humans and animals. Some species in this group are also associated with stored products like grains and cheese, and can cause skin irritations. House-dust allergies are often caused by species within the Dermatophagoides genus.12
