Clover Mite
Scientific Name: Bryobia praetiosa
Order & Family: Trombidiformes, Tetranychidae
Size: 0.75-1 mm (0.03-0.04 inches)

Natural Habitat
Outdoors on grass, clover, weeds, and various plants; indoors near windows, especially in spring and fall.
Diet & Feeding
Plant feeders, primarily feeding on clover, grasses, and other herbaceous plants by piercing plant cells and sucking out the contents.
Behavior Patterns
Clover mites are known for migrating indoors in large numbers, particularly during temperature changes (e.g., from warm to cold or dry to wet conditions) in spring and fall. They do not bite humans or animals but can be a nuisance due to their sheer numbers and the reddish-brown stains they leave when crushed.
Risks & Benefits
Potential risks include being a nuisance pest indoors due to their abundance and the stains they leave when crushed. They do not transmit diseases or cause structural damage. In gardens, heavy infestations can cause some discoloration or stippling on plants, but significant damage is rare.
