Our photo of the day illustrates the whimsical world of camouflage. Nobody ever said it was easy being a caterpillar. They have the misfortune of being high in protein and rather defenseless – making them an easy dinner target for other animals. But with this in mind, many have evolved various means of protection, like developing elaborate camouflage. Case in point: the is-it-an-insect-or-is-it-a-plant saturniid moth caterpillar, shown here in a photo taken by Andreas Kay in the rainforest of Ecuador. Look at all those leafy appendages the species has developed ... where is the caterpillar?! Would you like to see your nature photo featured as the TreeHugger photo of the day?
