|Larval harvest mite from North America|
It is the common chigger species of the United States, also sometimes called the harvest mite. Chiggers are the parasitic larval stages of these free-living mites. People in the dry Western states rarely if ever see them because the species prefers humid climates. They are commonly found in undergrowth and grassy brush areas; the larvae host on animals (e.g. reptiles, birds, and wild and domestic mammals), causing welts that can turn into dermatitis.
