Morphological features of Aedes koreicus larvae (a–c) and adult mosquitoes (d–i). The fourth-instar larva (a) carries setae with multiple branches in the frontal region of the head (b), while about 18 evenly spaced teeth are located on the siphonal pecten (c). Male (d) and female (e) adults show typical sexual dimorphism. The subspiracular area has a distinct patch of pale scales (f); the dark mesonotum harbors five defined lines forming a peculiar pattern with yellowish-brown or golden-yellow scales (g); the posterior femurs are characterized by a completely pale base (h), and the hind tarsomere IV shows the typical pale basal band (i)
