It will be easier to identify your spider once you post pictures, but if you look closely at it, you should be able to differentiate between wolf spiders and grass spiders by looking at the eyes and spinnerets.

With wolf spiders, the posterior median eyes (the pair of eyes in the middle of the back row of eyes) are significantly larger than the rest, like this: https://bugguide.net/node/view/12884 or this: https://bugguide.net/node/view/89936 while with grass spiders the eyes are more uniform in size like this: https://bugguide.net/node/view/715577/bgimage.

Also, grass spiders have long spinnerets like this: https://bugguide.net/node/view/1528986/bgimage while the spinnerets on a wolf spider are so small you barely notice them: https://bugguide.net/node/view/1574979/bgimage

Both wolf spiders and grass spiders can do well in captivity. Wolf spiders prefer a larger enclosure, with room to roam, and make very little webbing, while grass spiders prefer a secluded spot with plenty of attachment points for their funnel-shaped webs.

If he has long spinnerets, it's a grass spider. If it's a grass spider all it needs is something to start a funnel in (plant,sticks,substrate with starter hole). Super simple, they get all their moisture from their prey, but I still mist about once a week.

Personally, I keep a lot of wild-caught spiders. I would guess that for some of them, life might be just as comfortable in captivity as in the wild since they don't have to avoid predators anymore.

Living in the wild might not be all it's cracked up to be. This spring I watched a whole bunch of Araneus diadematus grow up from before they started ballooning all the way to adulthood. Many disappeared in the yard over the last few months. While they're slings, they have to avoid other spiders and predatory insects and as they grow, they have to avoid birds and other mammals. Sadly, I'm guessing a lot of my spiders in the yard were caught by predators. I caught about 10 of them at different points though during these months and I think I still have them all. From what I can tell, as long as they are kept right, their odds at survival are much better if they are kept as pets.

One exception might be if the spider is a mature male. Many don't hold onto those since they don't live too much longer usually after they're caught. Plus, if he's let go, you might have more next year. Another fun option, if you have a female, you could pair them up and have some babies! Ultimately, the choice is yours.

This is just my opinion but hope it helps .
