Harvest mite

Distribution

Trombiculid mites are found throughout the world. In Europe and North America, they tend to be more prevalent in the hot and humid regions. In northern Europe, including the British Isles where they are called harvest mites, the species Neotrombicula autumnalis are found during the summer and autumn, and in French harvest mites are called aoûtat because they are common in August. In the United States, they are found mostly in the South and the Midwest. They are not present, or are scarce, in far northern areas, high mountains, and deserts. In North America, the species Trombicula alfreddugesi is the most common, while the species Trombicula (eutrombicula) hirsti is found in Australia, where it is commonly called the scrub-itch mite.
