Help IDing caterpillar plz

[RED]

This little guy fell into one of my bug traps I put in the greenhouse maybe about a week ago, all thats in there(the greenhouse) is a dying pepper plant, some cacti,a young avacado tree/plant and some small fungi that just appeared once the tomato plants were finished.
I put him on a leaf snapped off the pepper plant, and thought nothing of it until I was putting the bins out a day or two later and noticed what at first appeared to be a slug (it was wet and very dark), but seemed too uniform a shape so I looked closer and it was, presumably, the same caterpillar.

I checked out all the pics on whatsthiscaterpillar and none seem quite right, neither did any on the first 10 pages on here either.

Any thoughts ?




I brought the leaf in with me when I brought him inside to take some pics, and he started eating it within a few mins, but the one I found in the greenhouse ate some of the pepper leaf before it moved on, so I'm at a loss to what it normally eats.
