In our experiments, mosquitoes were exposed to constant temperatures during larval, pupal and adult life stages. Therefore, we did not account for (diurnal or seasonal) temperature fluctuations which are experienced by natural populations and may affect the assessed life trait parameters. Also, it must be noted that we studied one population only. Genetic data suggest that the populations in Germany show population sub-structuring due to population admixture by active migration and repeated passive introductions [29, 32, 66]. Thus, local adaptation to temperature may vary among local populations and geographical regions. Thus, the generalisation of the data is difficult. That is why we focused our analyses on Germany only. For egg experiments, eggs collected in summer were used (Additional file 1: Table S1) thus presented results rely on non-diapausing eggs.
