The parasitic fly Ormia ochracea has incredibly sharp hearing to track down the exact location of its victims—crickets.

The work, described online today in Applied Physics Letters, could also come in handy to create gadgets that can pinpoint particular locations, such as where a gunshot came from, using only sound.
