This species is one of the largest mites in northern temperate zones, with a body length of about 4 mm. 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, 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 holo "whole" and seric- "silken".
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 like a grasshopper or diptere, but also arachnids like harvestmen or spiders. At this stage they are seen as red globules on their hosts, sucking body liquid without severely harming the host. These larvae then develop into free-living nymphs that resemble adults. T. sericeum is a palearctic species. Spotted in river Homem félinhos beach,a kind of acarus
