Anystides Red Velvet Mites or Rain Bugs are arachnids found in soil litter known for their bright red colours but are often mistaken for spiders. They are active predators as grown adults but as early instars are often parasites on insects.
Velvet mite in its natural habitat.
The pattern of stages is shared with that of other members of the Prostigmata: egg, pre-larva, larva, protonymph, deutonymph, tritonymph and adult (male or female). They usually have only one breeding cycle per year.
The oil from the red velvet mite Trombidium grandissimum is used in traditional Indian medicine to treat paralysis. Also, due to their alleged ability to increase sexual desire, Trombidium mites are known locally as "Indian Viagra."
