“Want to know how crickets choose mates? Well, listen closely next time you’re outside on a night when they’re singing. Very closely. It’s the males that are doing that chirping; they’re trying to attract females. But it took biologist Laurel Symes of Dartmouth College years of listening — and recording — to figure out that different species of cricket have different calls. She slowed down the recordings and discovered that what sounds like a continuous call to us actually has pulses — or rhythm.” w/ photos + audio clips
