From a this book of mites.
Luckily for us, these mites (the Oribatidae) aren’t parasitic. They live in dirt (which they turn, like earthworm), and eat lichens and fungus. They do serve as a host for tapeworms, so try not to eat them when you meet them.
As far as I can tell, this specific mite, Cepheus bifidatus, hasn’t been studied very much. At least, it’s sort of hard to find descriptions online. People do get very excited to find some of their cousins.
