Eutrombicula alfreddugesi
Eutrombicula alfreddugesi is a species in the genus Eutrombicula.
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. They are rarely seen in the dry Western states because the species prefers humid climates. They are commonly found in undergrowth and grassy brush areas; the larvae host on animals, causing welts that can turn into dermatitis.
