Biologists report that dragonflies capture their prey 95% of the time. That’s an amazing success rate. They’re such good hunters because they have huge eyes, four wings that move independently, and brains that allow them to track their prey as well as human hunters track theirs.
They’ve been successfully hunting for 300 million years. Our ancestors started walking on two legs about 6 million years ago.
Now, however, we’re letting our machines do the hunting (cf. the really cool drones in Oblivion, Tom Cruise’s latest). Much of the research on dragonflies is being sponsored by the Pentagon.
