Little orange worm

Here are four pictures of a small orange worm i took during last spring. I found the worm crawling on a stone staircase in my garden, and i thought it looked cute so i took some pictures of it. I don't know what kind of worm it is as it is the first time i have seen an orange worm in my area. I have seen plenty of green worms in my garden, but this is my first orange one.

Thank you for looking at my pictures.
