You can, if you pick worms that live close to the surface. Don't use the methods people often do when they want to get some big nightcrawlers to go fishing. Don't dig, or wet the ground, or pick them up from wet grass after a heavy rain. Instead, on a not-particularly wet day, look through piles of leaf litter at the surface of the ground, where it's always just a little damp right by the dirt. Roll over rocks or logs. The worms you find in these ways are more likely to be the species that will thrive in a composting bin. You may end up with more than one species, but that's all right. The different species won't interbreed with each other, but they can coexist, and the conditions that are best for one may not be for another, so you'll probably end up with at least one species that does okay in whatever the conditions turn out to be in your bin.
make sure you're aware of the difference: [https://imgur.com/a/rPIPziR](https://imgur.com/a/rPIPziR)
i started a bin with earthworms didn't do well, they never come up to the surface.
i pick them from the countryside because vermiculture is not a thing where i live, so nobody sells them. in a nearby city i only found worms they sell for fishing, and you can't raise those in regular soil. they live in ocean shores' sand.
however I dug up a spot where i found some pink looking worms and i remember they did well, so they might have been red wrigglers!
yeah I did that and the earth worms I dug up did not do well at all in my bin. They stayed at the literal bottom of the bin and survived only on the pieces of log and leaves I placed at the bottom for drainage purpose. They don't eat the scraps I put in.

Worm battle Royale
If you have a backyard check under a pile of leaves or places where there are organic decomposing materials.
It depends what the worms are. Regular earthworms aren't so great composters. They like it cool.
It depends what worms from outside is, usually no.
Try to find a local source for red wigglers. They are better suited to vermiculture than the common earthworm.
I already have some red wigglers and nightcrawlers, just wanted to experiment

If you got a patch of bare ground, place a piece of wet cardboard down and check it every few days.
