In the woods, I occasionally saw a dead leaf flying away on the tree technique, but in fact, it was not a dry leaf, it was a dead leaf butterfly flying.
Five. Mimicry. Now it resembles a dead leaf butterfly, but there are differences between its ancestors, and some of them do not look like dead leaves at all, and they are found and eaten by enemies. Some are slightly like dead leaves, which are not easy to find and survive. The surviving individuals pass on the mutation to the next generation, some of which are more like dead leaves, and those that are less similar to dead leaves are eaten by enemies. After a long period of time, the variation was passed down from generation to generation, and the mutation accumulated and strengthened from generation to generation, resulting in the dead leaf butterfly, which now resembles a dead leaf.
The front and rear wings of the dead leaf butterfly are semi-elliptical, forming a brown line when static, plus a few oblique lines, much like leaf veins. The color changes with the seasons and is yellowish-brown, reddish-brown, withered yellow, brown, etc. When the dead leaf butterfly is chased by birds, it flies in an irregular way, instantly lands in the leaves of plants, folds its wings, and stands still, just like dead leaves, and the birds that pursue it cannot find it, and can escape, this is its mimicry.
