DIY article on monitoring ultrasound from bugs

[DQE]

Sounds intriguing to listen to the sounds bugs make while we photograph or watch them.

Here's a link to an amateur radio magazine article on building and using a device to listen to such things:

Of course, we'll need to have a stereo version - no need to limit one's self to mono sound!

Does anyone recall much published or DIY work monitoring bug sounds? I am not thinking about the loud, easily human-audible sounds such as the ones crickets make of course. Maybe our bug friends are talking to one another intensively instead of working in silence as it seems?!?!

I hope this isn't yet another example of a topic I've proposed that has already been fully discussed on this most remarkable forum! All the search results I found were apparently related to ultrasonic cleaning of optics, etc.

I don't know about DIY but one of the staff (Broughton) at Sir John Cass College in London was recording aphid sounds in the late 1960s-early 1970s when I was studying there.

I can't begin to imagine aphids making sounds! Perhaps they make sheep-like sounds since they seem to function as cattle for ants? (grins)
