The sound you are referring here http://www.bbc.co.uk/nature/13958630
http://www.bbc.co.uk/nature/13958630, is the sound I recorded here in Italy and
I sent you on the previous post
https://soundcloud.com/marco- pesente/micronecta-sp-lesser- water
https://soundcloud.com/marco-pesente/micronecta-sp-lesser-water The other sound
I posted is refered to a water-boatman (Corixa punctata)

We first encountered these signatures in late March, 1984, at Mono Lake just
east of the Sierra Nevada Mountains along the Eastern border of California
while recording the Great Basin spadefoot toad (Spea intermontana) in a study
for the University of California in Santa Cruz led by the late Ken Norris (who
identified how dolphins generate and receive echolocation signals). We were
recording to see if the tadpoles generated sound (they do), and if the
vocalizations of the adults carried in water as well as air (they do). At the
same time, we picked up these odd scraping sounds (water-boatmen) but couldn’t
identify them, at first. But after filling some buckets with water and mud from
the pond, and sifting through the material, we were left with the water-boatmen
and were able to record them separately, thus figuring out the source.

Below the links to soundcloud for two of my underwater recordings from Italy.
Sounds are similar to that of your recording, but surely emitted by different
species of small aquatic insects.

Here's a water boatman from London, UK, that I heard in the wild then recorded
in captivity, in 1984. It was identified by an expert from our Natural History
Museum. I kept and bred it in captivity and it only ever sang with this rhythm
https://sounds.bl.uk/Environment/Listen-to-Nature/022M-LISTNAT00251-0001V0
Other species of course have their own distinct sound signatures.
Best wishes
Richard
