Mosquito.

Mosquito:

Large wings buzzing, buzzing
Such an uncomfortable sound
Stalks out it's victims
To gorge and quench it's thirst

To fill it's belly up
Moving on to another and then one other
Little bug, your carrying a disease
Unsuspecting it will make you sweat and freeze

A scourge on mammals
Their scent do you attract
This little blood sucker
Waiting for yet another attack
