They’re coming , and they’re Greek:

Cramped housing conditions and air pollution in Athens have given rise to a “super breed” of mosquito that is larger, faster and more adept at locating human prey, a Greek daily has reported.
Athens-based mosquitoes can detect humans at a distance of 25-30 metres (yards) and also distinguish colours, unlike their colour-blind counterparts elsewhere in the country that only smell blood at 15-20 metres, Ta Nea daily reported.
The “super mosquitoes” of the Greek capital also beat their wings up to 500 times a second — compared to 350 beats for other variations — and are larger by 0.3 microgrammes on average, the paper said, citing a study conducted by Aristotelio University in the northern city of Salonika.
