Mantis Egg Casings have appeared here more than once, but they are worth a closer look. Usually found on some type of plant (often, a tree), some mantises go for a gneiss spot. If you see holes in the casing, you know that a wasp took advantage of the slow hardening.
In the coming weeks, look for signs of mantises hatching.
