I’ve been doing some more hydrophone recording recently, and I often come across sounds of water bugs in bodies of water. I started looking for some information on the internet to help me identify them, but unfortunately there doesn’t seem to be much clear information on the internet for identifying water bugs by their vocalisations. I did find a couple of other interesting related resources though…
I found a study undertaken in Western Australia of the ambient sound field in some some freshwater wetlands in 2003, including a discussion of the invertebrate calls heard, but not identifying which particular invertebrates make which call. Here it is here:

Streamwatch have also got a great visual resource for identifying water bugs and how sensitive they are to water quality:

If you want to check out a sample of a hydrophone recording from a small dam with some water bug calls then you can find one at:
