Trombicula, known as chiggers, red bugs, scrub-itch mites, or berry bugs, are small arachnids in the Trombiculidae family. In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching and trombiculosis. These relatives of ticks are nearly microscopic, measuring 0.4 mm (0.01 in) and have a chrome-orange hue. A common species of harvest mite in North America is Trombicula alfreddugesi.
