Ormia ochracea is a small parasitic fly best known for its strong sense of directional hearing.
It’s no surprise that many bugs have excellent hearing thanks to finely honed antenna. Checking out the giant antenna on the tiny bug above, it seems no surprise that they can hear surprisingly well. In fact, some insect antennae are so powerful, engineers haven’t yet been able to come close to mimicking nature. And that’s especially when it comes to small, directional antennae. It’s one thing to have whip-like “ears” like the bug above, but what stumps engineers is making very small, but very acute sound sensors. Yet a minute fly — with minute antenna — is about to change that, and help revolutionize how we built these structures.
