How do you catch a tadpole?

Maybe CTM will answer because he has a tadpole in his pants.

A net. Or a jam jar with string to pull it up quickly when they venture in. I used to catch minnows that way. Of course they all died at home because they need running water.

But we just didn't know that.

Usually just a fine mesh net, like a butterfly net. Theyre not especially agile, so if you can find a pond with frogs around it, dip a net in and you should get something
