Multivoltinism likely influences the species’ evolutionary  and seasonal demographic dynamics . Compared to other mosquito species sharing the same larval habitat, the Asian bush mosquito occurs earlier in spring [35, 36] and usually displays multiple generations per year [35, 40]. The activity period of immature stages in native Japan starts in May . In Connecticut, USA, the activity period for immature stages ranges from March to November and adult females were active from June to October with highest abundances in September . In New York State, USA, Asian bush mosquito females were found from May to October , and in Switzerland, the last observed oviposition occurred in October . However, the number of potential generations per year is yet unknown and may depend on the particular environmental temperature regime in the area of occurrence.
