Found this Giant Leopard Moth Caterpillar munching away at our cactus. He will eat for a few days and then he will get to his busy work, forming a dense and silky cocoon in which to metamorphose (what a verb!). He will emerge from his chrysalis stage in two or three weeks, now a fully-formed moth, ready to fly off and find a mate, fully developed and prepared to continue a life cycle that has been going on for who knows how many millions of years.
