To our ears, the buzz of a mosquito is intensely irritating and a sign of itchiness to come, but to theirs, it’s a lover’s serenade. The high-pitched drone of a female is a siren’s song that attracts male mosquitoes. And a new study shows that when the two love-bugs meet, they perform a duet, matching each other’s buzzing frequency  with careful precision.

The female Aedes aegypti mosquito (the carrier of both dengue and yellow fever) beats her wings with a fundamental frequency of about 400Hz, producing a pitch just slightly lower than concert A. Males on the other hand, have a  fundamental frequency of around 600Hz, about one D above middle C.
