Observations by mattmaves

What do I do? Please inform. This is what I think is a the tobacco hornworm Pupae. I found one under a tree, in a concrete area in my back patio. It was amongst Widows and I know Roaches roam around, it would have been killed. I'd like to know what to do with it? I have researched a good amount online and have found a good amount of info on rearing Pupae for personal observation, which is all well and good. But I would rather put it in an ideal natural location and I'm not home enough to take care of them. Moth Pupae are buried as opposed to hanging, which doesn't make sense that I found it as though it had fallen from a tree. I originally put him in a small hole in a grassy area and covered it with leaves and sticks, but I honestly don't know 100% what it is and I am in a condo that is sprayed with pesticides and dogs romp around and it just wasn't a good idea to leave it there. So I took it inside and put him in a jar with dirt and leaves. While rinsing leaves outside for him I found another in the same predicament, So If anyone has some direction, I would be very grateful.
Thank you
