Mosquito
Mosquitoes of the genus "Toxorhynchites" never drink blood. This genus includes the largest extant mosquitoes, the larvae of which prey on the larvae of other mosquitoes. These mosquito eaters have been used in the past as mosquito control agents, with varying success.
Aedes koreicus
Aedes koreicus is a mosquito species originally described from Korea that has been shown to be enzootic to Japan, northeastern China, the Republic of Korea (South Korea) and parts of Russia, but recently found in Belgium and Italy. Adult "Aedes koreicus" are relatively large, with areas of white scales on black background, strongly resembling "Aedes japonicus", which has also become established outside its native range.
