Identify what this is?
I have seen on my patios, debris that I thought was coming from my roof shingles. I’ve taken a better look at it when sweeping and it looks like a shell. Is this an insect? It doesn’t move so I assume they are dead. Please help me identify what this is, I will include a picture of some I collected. I have watched you for years and have enjoyed all, thank you for being so informative.
