It's been several years since the rumors and sightings of insect sized micro drones started popping up around the world.

Vanessa Alarcon was a college student when she attended a 2007 anti-war protest in Washington, D.C. and heard someone shout, "Oh my God, look at those."

"I look up and I'm like, 'What the hell is that?'" she told The Washington Post. "They looked like dragonflies or little helicopters. But I mean, those are not insects," she continued.

A lawyer there at the time confirmed they looked like dragonflies, but that they "definitely weren't insects".

And he's probably right.

In 2006 Flight International reported that the CIA had been developing micro UAVs as far back as the 1970s and had a mock-up in its Langley headquarters since 2003.

While we can go on listing roachbots, swarming nano drones, and synchronized MIT robots — private trader and former software engineer Alan Lovejoy points out that the future of nano drones could become even more unsettling.

Lovejoy found this CGI mock up of a mosquito drone equipped with the 'ability' to take DNA samples or possible inject objects beneath the skin.

According to Lovejoy:

Such a device could be controlled from a great distance and is equipped with a camera, microphone. It could land on you and then use its needle to take a DNA sample with the pain of a mosquito bite. Or it could inject a micro RFID tracking device under your skin.

It could land on you and stay, so that you take it with you into your home. Or it could fly into a building through a window. There are well-funded research projects working on such devices with such capabilities.
