In (sub-)tropical invasive mosquitoes, e.g. the Asian tiger mosquito, the temperature is the dominant factor limiting the species’ distribution in mountainous regions . In the temperate Asian bush mosquito, temperature also limits the distribution as pointed out here and temperature-dependent development data may be included in species’ distribution modelling. Besides the Asian bush mosquito, Aedes koreicus is also a temperate mosquito species which arrived in Germany . This further introduction highlights the importance of studying ecological and physiological features of temperate mosquitoes to allow predictions on key risk areas and future distributions.
