Description
Dipeng Ren and colleagues listen with a microphone modeled on a fly's ears. The parasitoid fly Ormia ochracea pinpoints crickets using two coupled ear membranes, inspiring tiny directional microphones. Their 2026 optical version has unusually low damping, letting a second vibration mode ring clearly.
That bending mode hears from all directions, while the rocking mode favors two. Layered together, the modes paint shifting directional patterns, from split lobes to twin circles that gradually merge. A theory model tracks the whole transition neatly. Surprisingly, the separated circle patterns locate sounds just as well as the classic two-lobed one.
