Unknown animal in my garden

[Hydroponics Curacao]

Hi,

I was taking the pepper plants out of my raft system and putting them into half drums. Where the other peppers are. And I've planted some papayas into the system so they can grow fast. And when they are big enough, I will transplant them into soil. The papayas are for my worms. 

Well, when I was digging holes in the half drums, I came across a worm that I haven't seen before. It is still alive and I've put it back into the drum after taking pictures of it. I know that it cannot be a butterfly because they don't live in soil. Or do some of them? 

I put it back because I didn't know if it was helpful in my garden or not. The peppers that were growing in there are doing wonderful and haven't had any diseases. I thought that maybe that worm helped with that. I don't know. 

Here are some pictures. Please let me know if you know something about this animal

I'm just gonna say that something that stinkin' ugly does not belong in your garden. (that is not a roly-poly bug) That's a big 'ole grub. If you are really unsure whether or not its beneficial, squish it and use it as fertilizer so it won't go to waste :)

Hahahhaha. Well thanks for all your help. After that one, i haven't found any of them in my garden anymore. I think there was something that attracted them to go there.

Cool. I vote we stop resurfacing this thread, 'cause I feel like I'm gonna throw up. And this is coming from a guy that thinks bsf larvae and redworms are "cute". Usually, people are too vague on their pest problems, I'm giving you props for providing PLENTY of detail.
