Red Velvet Mites (Rain Bugs) Trombidiidae Aristocratic arachnids swathed in crimson coats of the plushest velvet. In the warmer months, wander around the wood after it rains and you’re sure to see more than a few of these crawling-carbuncles afoot. They are harmless to humans. In India, an oil extracted from the giant red velvet mite has been used to treat paralysis. They’ve also been implemented as an aphrodisiac (also in India).
