Oak has been rejected as a host of this species. It also feeds on the surface of developing fruits and may foul them with its webbing. Adult females overwinter, often hiding in colonies under mosses on the bark of host trees. In spring, the females begin to feed on the early developed leaves, around the 10 th of April in Switzerland. Eggs are deposited after about 10 days of feeding, and they hatch in about fifteen days.
Young mites begin to feed on newly developed flowers.
Depending on weather conditions, in Switzerland, up to six generations per year may develop. In Japan, the adults appear on the leaves of the host from the end of May to the beginning of June. During this time females lay eggs. Locally the mites may spread from leaf to leaf and from plant to plant. Also they may spread incidentally on other organisms or on leaves blown by the wind, or perhaps by air drift alone.
