Found this in the remnants of a bag a grass seed from last year. It seems completely desiccated.

My best guess is that this is what we call a worm snake. I can't imagine how it got there unless it came with the bag. The bag has been in my garage since I bought it.

We've got a lot of these worm snakes on my property. They're smaller than a lot of earthworms I find (that's engineering paper, 5 squares per inch).
