A green (duh) leaf insect. Its big! It must be three or four inches long, plus another three inches to the tips of its leafy wings. Speaking of which, those wings are an incredible example of mimicry, they are the color and shape of a leaf (I don't know what kind of leaf, just, like, a generic, plutonic ideal of a leaf, you know). There are veins, a lighter green in color, branching across them just like the veins in a leaf. Wild.
