Clover Mite
Scientific Name: Bryobia praetiosa
Order & Family: Trombidiformes: Tetranychidae
Size: 0.75 mm - 0.85 mm (about the size of a pinhead)

Natural Habitat
Grassy areas, lawns, and gardens; commonly found on building walls, windowsills, and outdoor furniture during spring and autumn.
Diet & Feeding
Herbivorous; they feed on more than 70 species of plants, primarily sucking juices from grasses, clovers, and certain shrubs.
Behavior Patterns
They are most active during cool weather. They reproduce through parthenogenesis (females can produce viable eggs without mating) and often mass-migrate into homes during sudden temperature shifts.
Risks & Benefits
They do not bite humans or pets and do not cause structural damage. However, if crushed, they leave a red stain that can ruin fabrics or carpets. In the ecosystem, they serve as a food source for other predatory mites and insects.
