Pyemotes is a genus of mites (Acari) from the order of the Trombidiformes . It consistently contains insect parasites that live mainly on beetles and bees .

The genus is divided into two groups, the scolyti group and the ventricosus group. Species of the former group are parasites of bark beetles and at least one morph of the females lives phoretically .

Some Pyemotes TYPES can dermatitis trigger in humans. It is caused by parasitic species in insects when the primary host is not available to them; the human being is therefore a false host in these cases. The reddened and itchy wheals that are triggered can become very annoying. The following are known to be responsible for this: Pyemotes tritici , in people who work with straw or grain stores, the actual hosts of the species are larvae of beetles or butterflies that are harmful to supplies. (In older publications the species is still classified as Pyemotes ventricosus .) Pyemotes ventricosus in people who have been in contact with old wood or old furniture. The real host of the mite species are "woodworms" (the larvae of the common rodent beetle , Anobium punctatum ). In some regions of North America, many thousands of people exhibited red wheals caused by Pyemotes herfsi . This species parasitizes, along with other hosts, gall midges of the genus Contarinia , which cause plant gall on oaks. The legs were particularly affected, presumably by mites that had fallen from trees.

The genus includes the following species (Europe):
