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

Natural Habitat
Typically found in grassy lawns, clover-rich landscapes, and gardens; often enters homes through small cracks in windows and doors during spring and fall.
Diet & Feeding
Herbivorous; they use their mouthparts to suck juices from over 200 species of plants, including grasses, clover, and ornamental flowers.
Behavior Patterns
They are active in cooler temperatures (late spring and autumn). They reproduce parthenogenetically (without males) and often aggregate in large numbers on sunny walls or indoors when conditions outside become too hot or cold.
Risks & Benefits
They do not bite humans or pets and do not transmit disease. They are considered a nuisance pest because they can leave reddish-brown stains on upholstery, curtains, and carpets if crushed. They play a minor role in the ecosystem as a food source for other predatory mites.
