Trom·bic·u·li·dae

(trom-bik'yū-lī'dē),

A family of mites the larvae of which (redbugs, rougets, harvest mites, scrub mites, or chiggers) are parasitic on vertebrates; its nymphs and adults are bright red and free-living, living on insect eggs or minute organisms in the soil. The six-legged larvae are barely visible red or orange parasites that attach to the skin for a few days to a month, producing an exceedingly irritating reaction. In Asia, trombiculid chiggers of the genus Leptotrombidium transmit tsutsugamushi disease, caused by Rickettsia tsutsugamushi, which is transovarially transmitted in these mites.
