Clover mites can overwinter at various stages in their lifecycle (egg, nymphs, and adults), but generally do so as eggs in the oviposition sites mentioned above. They appear either in late fall or early spring.
Their main food source is sap from herbaceous plants, including lawn grass. They move back and forth from the shelters where they molt to the plants on which they feed. Clover mites can be a pest due to their mere presence and because of the red stains they leave when crushed.
