About Astigs: the wider group
Order-level background for Astigmata, the group containing Sancassania anomala. Species-specific details appear above.
Group overview
Astigmata includes ~6,000 described species of mites, including dust mites, scabies mites, and cheese mites. House dust mites (Dermatophagoides) are present in virtually every human dwelling.
Ecological role of the group
Astigmatid mites are important decomposers of organic matter and recyclers of nutrients. Many species are phoretic - hitching rides on insects to reach new food sources like decaying material, stored grain, and animal nests.
Economic and practical significance of the group
Dust mites are the primary trigger for allergic asthma - affecting ~300 million people worldwide (WHO). The scabies mite causes an estimated 200 million cases of scabies globally. The global allergy treatment market partly driven by dust mites exceeds $25 billion.
