Bug's "Bird Poop" Disguise
This larval swallowtail butterfly's clever disguise (left) is literally a load of crap.
In its larval stages, the Asian swallowtail—also known as the Chinese or Japanese yellow swallowtail—mimics the appearance of bird droppings to prevent predators from gobbling it up.
In its last phase of development, the insect turns green (right) to blend into the leaves on which it lives.
