Sorry I accidentally deleted my last post. I appreciate the answers the two people gave.
This is some big larva I found and the head looks centipede-ish but the body is short and fat with less legs.
I went through my images and found an old photo of a beetle that was on my screen door. Maybe it's a larva for one of these?
That's how I know them as well, around compost heaps these yellow and black beetles hover, and then you find those guys in the ground, but I am south African so that might be why I know them as cutworms
