Trombidiformes Genera
Trombidiformes is a large, diverse Order (biology), order of mites. Taxonomy In 1998, Trombidiformes was divided into the Sphaerolichida and the Prostigmata. The group has few synapomorphy, synapomorphies by which it can be defined, unlike the other major group of Acariformes, acariform mites, Sarcoptiformes. Its members include medically important mites (such as ''Demodex'', the Trombiculidae, chiggers, and Trombicula, scrub-itch mites) and many agriculturally important species, including the spider mites (Tetranychidae). The superfamily Eriophyoidea, traditionally considered members of the Trombidiformes, have been found to be basal mites in genomic analyses, sister to the clade containing Sarcoptiformes and Trombidiformes. The 2004 classification retained the two suborders, comprising around 125 families and more than 22,000 described species. In the 2011 revised classification, the order now contains 151 families, 2235 genera and 25,821 species, and there were another 10 spe ...

Trombidium Holosericeum
''Trombidium holosericeum'' is a species of mite in the genus ''Trombidium''. It occurs in Europe, Asia, and Africa and is commonly confused with other red mite species. Description This species is one of the largest mites in northern temperate zones, with a body length of about ). The soft, brightly red body is covered with fine hairs, giving it a velvety appearance. The small eyes are located on stalks. They have scissor-like chelicerae and their pedipalps are used as touch organs. Its bright red color results from carotenoids, warning predators about the toxicity of the mite (aposematism). Almost nothing is known about the toxic substances used, but they are probably contained within the integument. The specific epithet is derived from Ancient Greek , , "whole" and , , "silken". Biology While adults live freely and are often found wandering about, searching for small animals and insect eggs for food, the larvae try to find a host to attach themselves to, often an insect li ...
