The foliage usually turns yellow or brown and then wilts. The winter eggs hatch and give rise to a spring generation, or the over wintered adults deposit spring eggs, the progeny of which also become a portion of the spring generation. The over wintering larvae and nymphs mature in the spring, their progeny forming a slightly delayed portion of the spring generation. The mites over summer in the egg state. With a drop in the temperature, often in late September, the eggs start hatching .
Hatching commonly occurs on sunny days during the winter on the south side of dwellings and trees.
The mites migrate to their host plants as mite activity increases in the spring. Eggs may hatch after a week with temperatures at 28 to 46 degrees F will hatch in 12-18 hours. The winter adults also have a very low threshold of activity, so become active and begin depositing eggs about the same time as winter eggs begin to hatch. Over wintering adults continue to oviposit until mid-April. Some fields got better and some did not.
