Mosquito or a insect spy drone.

UNREAL... "Is this a Mosquito? No. It's an insect spy drone for urban areas, already in production, funded by the US Government by way of OUR very own tax dollars. It can be remotely controlled and is equipped with a camera and a microphone. It can land on you, and it may have the potential to take a DNA sample or leave RFID tracking nanotechnology on your skin. And for all of you who are quick to say it must be "fake" because you don't think the government could possibly be funding anything such as this... do some research."
