Common house mosquito
Culex pipiens

— Where the name comes from
Culex is the Latin name for the mosquito. Pipiens means “cheeping”, from the verb pipire that the Romans used for the sound of chicks: it is the high whine heard in the ear in the dark, described by those who suffered it as the peeping of a small bird. The Italian name comes instead from the vulgar Latin zinzala, equally imitative.

— What sets it apart
The whine is not an accidental noise but a call: when male and female meet in flight they adjust the frequency of their wingbeats until the two sounds agree on a shared harmonic, around twelve hundred hertz. It is a duet, and it serves to recognise the sexes. In the tunnels of the London Underground a form has become isolated that does not overwinter, bites mammals rather than birds, and no longer interbreeds with the surface population: a species in the making, born in a century and a half inside a tunnel.
