Some say imitation is the most sincere form of flattery, but ulterior motives abound in the animal kingdom. Biomimicry is the imitation of a natural phenomenon, and in this dog-eat-dog world — or rather, for this example, bird-eat-insect world — riding the coattails of a successful species may be the ticket to survival.
For example, both Monarch and Viceroy butterflies have a very similar appearance (despite belonging to different genera), and both contain toxins that make them an unpleasant meal.
As these two species evolved towards a common appearance, they benefited from an increased chance that a predator had already learned to avoid orange and black striped butterflies after suffering from a bitter taste and an upset stomach. In this case, both species benefit by looking the same (which scientists call “Müllerian” mimicry) as they both get eaten less.

But of course, not all mimics help each other out. In some cases, just as you’ve built up a tough reputation by spending a lot of energy developing natural defenses, some punk copycat shows up looking for a free ride.
For example, many bees, wasps and hornets share a pattern of alternating yellow and black stripes (another example of Müllerian mimicry). But since so many predators have learned to avoid them, they are also a popular target of “Batesian” (or freeloading) mimics. From moths to flies to beetles, many harmless insects have found that as long as their population size is low relative to their more dangerous lookalikes, predators will play it safe and avoid them too.

Biomimicry isn’t always about insect survival. Humans mimic animals and there are a number of amazing animals that copy us right back.
From simple examples like house sparrows learning to open automatic doors to impressively complex ones (see the video of an orangutan stealing a canoe, paddling out to a boat, stealing a fish trap and eating the fish), it might not be long before the idea of dogs playing poker doesn’t seem funny anymore.
Now that we know that crows can not only recognize our faces but describe us to other crows, we might want to step up our game before they figure out the best way to put us to work for them. Be sure to check out Biomimicry News to keep track of our progress!
