Ewing, 1938

Eutrombicula is a genus of mites in the family Trombiculidae. The species of this genus are found throughout North America, and Australia. [1]

Contents

The genus was first described by Henry Ellsworth Ewing in 1938. [2] [3]

Two genera of chigger mites, each containing many species, are of concern to U.S. deployed military forces. They are Eutrombicula and Leptotrombidium . Chiggers in the genus Eutrombicula, such as Eutrombicula alfreddugesi, do not transmit any known pathogens to people, but they can cause irritating bites, dermatitis and severe itching when they feed on the unsuspecting host. They are widely distributed in the Western Hemisphere, and Europe. By comparison chiggers in the genus Leptotrombidium are the vectors of scrub typhus throughout Asia and portions of Australia. The bite of Leptotrombidium often does not itch, or at least not as intensely, as those of Eutrombicula. Also, a black necrotic lesion known as an eschar develops where the chigger fed. [4]

<i>Trombicula</i> Genus of arachnids

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; in the UK, the most prevalent harvest mite is Trombicula autumnalis.

Chiggers are tiny harvest mites, members of the family Trombiculidae, that can cause intense itching and dermatitis.

Mesostigmata Order of mites

Mesostigmata is an order of mites belonging to the Parasitiformes. They are by far the largest group of Parasitiformes, with over 8,000 species in 130 families. Mesostigmata includes parasitic as well as free-living and predatory forms. They can be recognized by the single pair of spiracles positioned laterally on the body.

Orange leaf-nosed bat Species of bat

The orange leaf-nosed bat is a bat in the family Hipposideridae. It is the only living species in the genus Rhinonicteris which is endemic to Australia, occurring in the far north and north-west of the continent. They roost in caves, eat moths, and are sensitive to human intrusion.

Leptotrombidium is a genus of mites in the family Trombiculidae, that are able to infect humans with scrub typhus through their bite. The larval form feeds on rodents, but also occasionally humans and other large mammals. They are related to the harvest mites of the North America and Europe.

Trombiculidae Family of arachnid mites

Trombiculidae ; commonly referred to as chiggers, but also known as spider mites, berry bugs, harvest mites, bush-mites, red bugs or scrub-itch mites, are a family of mites. Chiggers are often confused with jiggers - a type of flea. Several species of Trombiculidae in their larva stage bite their animal or human host and by embedding their mouthparts into the skin cause "intense irritation" or "a wheal, usually with severe itching and dermatitis",
