The eggs of the Asian bush mosquito are extremely resistant, they survive freezing temperatures and drought. This ability enables it to emerge anywhere as soon as the weather gets good enough. However they are limited by extremely hot temperatures: above 30°C they can’t develop, which can restrain their spreading in the future. They overwinter as eggs in their native habitat in Japan and Europe as well. The freeze and desiccation-resistant eggs can survive unfavorable conditions for years and hatch once environmental conditions become favorable again, i.e. when they are covered by stagnant water and the temperature is right, they  begin to develop. Larvae can be found in both natural and artificial water bodies which can be as small as few liters or less to serve as ideal breeding sites. In their natural habitat, they usually develop in tree holes and rock pools, but they thrive in urban areas as well: tires, bird baths, vases placed on graves, rainwater containers, barrels, watering cans, buckets or milk boxes are suitable for the development of the larvae. The larvae begin to filter-feed immediately after hatching, their food consists of particulate organic matter, bacteria, and unicellular eukaryotes. The  biting adults of Asian bush mosquito are active until late autumn in its native range, and it has many generations through the year. In Europe its season of activity begins in May and can last until October, its reproduction can decline in the hottest months of summer, being more abundant in early summer or early autumn. Adults are active during the day and at sunset, and aggressively attack humans even indoor, but they feeds on other mammals as well.
