Mosquito Effort and Fate

It was tropical night, hot humid and wet, They were all here, buzzing now here now there, they had a method, by which they sucked blood, they would go in a flight, path of which was out of human sight, they would fly against miscible background, now straight and now round, they would land carefully on the unwary, behind ears lobes ,on the neck, arm elbows and toes, all I could not understand, why they made an intense buzzing sound, just before landing down, perhaps it was their war cry, and they were challenging human victim , that we can take you on, though all landing strips were out of reach, of a crushing swat, and that probably made for their screech and voice, once settled they would sink in probe, and suck in belly, human blood, now that human was had, the mosquito was more than glad, it would free itself and fly to incubate, but I have not seen any creature, that takes so much risk, and gets killed often, because of the thing they just ate.
