Trombiculidae (/trmbkjuldi/; also called berry bugs, harvest mites, red bugs, scrub-itch mites and aoutas) are a family of mites. The best known of the Trombiculidae are the chiggers. The two widely recognized definitions of ''chigger'' are the scientific (or taxonomic) and the common, the latter of which can be found in English and medical dictionaries. According to most dictionaries, the several species of Trombiculidae that bite their host in their larval stage and cause ''intense irritation'' or ''a wheal, usually with severe itching and dermatitis'', are called chiggers. The scientific definition seemingly includes many more, but not all species of Trombiculidae.
