Trombicula alfreddugesi, also called Eutrombicula alfreddugè, is a species in the genus Trombicula. (Eutrombicula is a subgenus of mites in Trombicula of the family Trombiculidae.[1])

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.[2] It is rarely, if ever, seen by most people in the dry Western states because they prefer humid climates.[3] They are commonly found in growth 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. See chiggers.
