Red Velvet Mite
Trombidiidae · also called rain bugs
Emerging from the soil by the thousands after the season’s first heavy rain, red velvet mites blanket the ground in a sudden burst of vivid colour, their soft, velvet-textured bodies ranking among the largest and most visible of all mites.
Overview
The red velvet mite, family Trombidiidae, is native to grassland and forest soil habitat across many regions of the world. Its vivid red, velvety appearance, dramatic post-rain emergences, and unusual shift from parasitic larva to predatory adult make it one of the most visually striking and behaviourally distinctive mites found anywhere.
A life that changes strategy completely
Few animals switch feeding strategies as dramatically as the red velvet mite, beginning life as a parasite riding on another arthropod before transforming into an active, independent predator once it reaches adulthood.
Status
Not Evaluated for conservation status, found across suitable soil habitat throughout its range.
Red Velvet Mite: common questions
Why do red velvet mites suddenly appear after rain?
They emerge from the soil in large numbers shortly after heavy monsoon rains, a striking and highly synchronised event in regions where seasonal rainfall is pronounced.
Are red velvet mite larvae the same as the adults?
Not in behaviour; the young larval stage is parasitic on other arthropods such as grasshoppers, while the adult instead switches to actively hunting small insects and their eggs.
How big does a red velvet mite get?
It reaches a size that is unusually large for a mite, making it one of the few mite species large enough to be easily seen with the naked eye.
Where are red velvet mites found?
In soil across grassland and forest habitat in many regions of the world, with particularly well-known populations in monsoon-affected areas of Asia.
