Trombicula alfreddugesi, also called Eutrombicula alfreddugesi, 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] They are rarely seen in the dry Western states because the species prefers humid climates.[3] 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.
