We decided to move the mantis to a better location - a nearby garden. Although the mantis probably could find plenty of food on the side of the building, it was a little conspicuous right next to the door. We figured a garden full of green plants would be a better place for its long term survival.
This individual is a nymph. It will pass through approximately ten stages of life (instars) before it becomes an adult, molting its exoskeleton each time. I can tell this is a nymph because it lacks wings; adults of both sexes will have wings, but large females are often too heavy to fly.
