Origami

There are a lot of well-known architects and engineers in the animal world: beavers, paper wasps, termites,  and naked mole rats come to mind. Just within my garden, a variety of critters create shelter using plant leaves. Any stroll will reveal leaves folded or rolled and sealed with silk. I opened up a leafy taco-shell, causing a spider to rush out in arachnid rage, shouting the spidery equivalent of "Get off my lawn!"

This caught my eye on a recent dog-walk. I've never seen a shelter shaped like this one. I don't think I could create it with my ten fingers and big brain.
