The story comes with a picture claiming to show a Mosquito spy drone that can take photographs and DNA samples of people, and that it is funded by the U.S government for tracking people.
It is a fact that there are reports suggesting that research is going on to develop the MAV's, i.e. Micro Air Vehicles in the form of tiny flying objects like a mosquito. The purpose of these MAVs is to be useful in scientific and military applications. The micro flying robot can have cameras, microphones and other sensors that can take pictures, videos and other useful scientific and biological information from people and places where humans (or the military) cannot reach. This way the tiny flying robots can also be used as spies and weapons against enemies.
The picture shown in the story is not a real robot mosquito drone, but simply one such proposed 'prototype' that may become reality in future, and perhaps they will also be able to take photographs and DNA samples of people. But as of now, these are only speculations, and not facts in practical.
