Trombidiidae


Trombidiidae, known as red velvet mites, true velvet mites, or rain bugs, are arachnids found in soil litter known for their bright red color. Red velvet mites are active predators as grown adults but as early instars are often parasites on insects and some arachnids. They are sometimes mistaken for spiders.
The pattern of stages is shared with that of other members of the Prostigmata: egg, pre-larva, larva, protonymph, deutonymph, tritonymph and adult. While adult true velvet mites are typically in length, some, such as the genus Dinothrombium, may reach up to. They usually have only one breeding cycle per year.
One well known species from Europe, Asia, and North Africa is Trombidium holosericeum. The systematics of this group has been in flux and many former subfamilies of this are now raised to families within the Trombidioidea.

The oil from the red velvet mite Trombidium grandissimum is used in traditional Indian medicine to treat paralysis. "
