Found some larvae in local vernal pools. I know a person who owns an aquatic invertebrate shop in South Korea so hopefully, he'll be able to tell me some tips on rearing this genus.

Awesome! I've been looking for diving beetles for a while, hopefully I find some come spring. I didn't know these were popular in South Korea, are they pretty successful with breeding?

CA has lots of interesting diving beetles so hopefully you'll find some cool species in your area

Diving beetles in genus Cybister are one of the popular pet insects in South Korea so there are lots infos and successful breeding reports on them available online. Dytiscus however, are very rare in South Korea (the fact that they are usually collected in areas near DMZ zones makes them harder to obtain) and as far as I know only 3~5 people in South Korea have kept them in captivity (and the person I'm going to ask is one of them).

 
Hopefully, I have a list but the hard part is getting to the right places at the right times.

That's really interesting, I didn't know pet insects were popular in South Korea. I knew they were popular in Japan, and crickets are common in China and Vietnam, but I wish they were more popular here.

 
Is there any information in English about rearing or breeding Cybister, I have had 3 in a tank on my windowsill for the last 9 months but unfortunately do not speak Korean.

Your Dytiscus larvae should eat anything small and live added to the tank - it will need to pupate on land when fully grown.

Unfortunately, I don't have any english version of breeding guide for Cybisters, but if it is about not getting eggs from your adults I would suggest using water hyacinth for oviposition (I would recommend placing at least 10 plants in the tank).

I'm waiting on a container for setting up an environment suitable for raising larvae and pupation. Hopefully, it will arrive soon and I'll be able to work on it before my larvae mature

Cool find! In the summer I see huge swarms of driving beetle on the Wekiva River near shady spots free from sunlight.
