The CIA had a robotic dragonfly that flew 40 years ago...think about what they might have today.

In the 1970s the CIA had developed a miniature listening device that needed a delivery system, so the agency’s scientists looked at building a bumblebee to carry it. They found, however, that the bumblebee was erratic in flight, so the idea was scrapped. An amateur entomologist on the project then suggested a dragonfly and a prototype was built that became the first flight of an insect-sized machine.

A laser beam steered the dragonfly and a watchmaker on the project crafted a miniature oscillating engine so the wings beat, and the fuel bladder carried liquid propellant. Despite such ingenuity, the project team lost control over the dragonfly in even a gentle wind. “You watch them in nature, they’ll catch a breeze and ride with it. We, of course, needed it to fly to a target. So they were never deployed operationally, but this is a one-of-a-kind piece.”
