How to catch land beetles?

Hello.
I played a lot and now I want to try something new.
I decided to go fishing for insects (or animal husbandry).
The game has a butterfly net, with the help of it you can catch flying insects, such as butterflies.

But, the problem is how to catch ground beetles?The game has a lot of crawling bugs, such as lizards, rabbits, and so on.Net they can not be caught.And if you try to kill them with 50 hp, then it is impossible, because they immediately die.Is it possible to still collect a collection (catch) crawling bugs?

Another question about the bait.Does fishing work on the principle of minecraft? You can throw the bait in any puddle and fish will be caught from there?
