Trombiculidae

Adult harvest mite Trombicula, photographed by Alan R. Walker.


Belongs within: Trombidia.

The Trombiculidae are a family of predatory mites whose larvae, known as chiggers, are mostly ectoparasitic on vertebrates. Bites from chiggers induce formation of a characteristic feeding tube, the stylostome, and can cause intensely itchy lesions that may become infected. Adults, where known, are predators, often of insect eggs (Walter et al. 2009).

Characters (from Kethley 1990): Adults and nymphs with anterior margin of prodorsal sclerite with two, one or no setae; prodorsum with one pair of flagelliform trichobothria; pregenital tubercle absent; setae on palp genu more numerous or equal to those on palp femur; palp tibia with two distinct spines in tandem near large clawlike seta. Larvae with prodorsal sclerite with a single anteromedian seta (unpaired vi); anal sclerite absent; genu II with three branched setae.
