Where was it recorded?
This sounds like a Micronecta species.

This is a pretty cool recording. It sounds like a field of
goldenrod in mid to late summer! -- maybe these are the sounds of
stridulating aquatic beetles (hydrophilids, gyrinids, dytiscids?)
and water bugs (corixids, nepids, notonectids?). Very little is
known about sound production & communication within such

Our aim is to record underwater fauna activity in relatively
small lakes and ponds.
The recording device we are using is a mere Tascam DR100 that
delivers 48V phantom power and ideally we'd like to avoid
hydrophones needing an additional preamp.
We already experimented with cheap and handmade solutions,
like piezoelectric transducers, with often quite nice results
(well, for our application anyway...)
Here's an example of what we have recorded with some piezo

That was recorded in a pond. Using the same piezos in a lake,
nothing like that was picked up, all was silent (except some
far away motorized boats).
So, do you think investing in some low-cost hydrophones we
may achieve better results than the example above? Will it
allow to record some more details?
