Animal science: Fruit fly with an animal tattoo?

gtridens fruit fly

The fruit fly Goniurellia tridens is an amazing insect, since it carries very distinct engraved or tattooed ants by nature on it’s wings. When you look at photos, you immediately think that a Photoshop artist made that, but this is not the case. This fly really exists and is currently irritating scientists, who can not explain this phenomenon. As a rule, in science it is assumed that signs on hulls or wings have the meaning to ward off natural enemies. Think of wasps, which are black-yellow striped and want to signal danger in the animal world in order to scare their enemies. It is really surprising, that the Goniurellia tridens has ants on its wings, since ants are not really scaring animals or able to stop bigger birds or insects from eating the fruit fly. Because of this reason, you might wonder, why the fruit fly is carrying two ants on her wings?

First of all, apart from how these “ants” could even get on the wings of this fruit fly, there is not only a single fruit fly that I am talking about, it is a species – and you should ask, what sense is this having? So far, there only exist theories. For example, it is claimed, that these are no ants, but spiders, which are used as a deterrent. This is not only inaccurate, but weird, because it is clearly recognizable that these are ants, but it is also quite unlikely, because these spiders would be extremely small and hardly impressive.

Another theory is, that if a natural enemy discovers ants on the fruit fly, he might assume that the fly is already dead, and the ants have already made their way it. This theory is also questionable, because as soon as the fly composes its wings, it looks like the “ants” move away from the fly. So far the theories do not explain the deterrence of this tactic. In my opinion, it is at least true that in nature much mimicry is practiced, like a furtive or deceptive behavior, to look like more than you actually are. Think of the peacock, for example, who opens his feather dress to impress. The many peacock eyes on the feathers might give the impression that the opponent suddenly had to deal with twenty peacocks. Or think of the huge atlas moth, whose wingspan reaches a size of 25 cm! She wears two colorful snakes on the back of her wings. You have to look twice to find the snakes, but when you look at the top edges you can quickly see two real snake heads in the profile. The insect also surprised with an excellent imitation or mimicry.

The fruit fly G-Tridens was discovered on a rosebush bush by Dr. Howarth. After his discovery he said:

“I was looking at the trunk and the leaves of the bush when I noticed that some insects crawled on it. Then I thought it was an insect whose wings were attacked by ants, but they were arranged too symmetrically. Shortly after, I realized that it was just an insect.”

Later Howarth took the insect home with him and placed it under a microscope:

“It was amazing! Under the microscope I discovered that on the wings of the fly ants had been painted. In contrast to her wings, she had brilliant, green eyes, and the body was a little greenish-almost cryptically colored.”

Howarth researched and conversed with other researchers. One of his colleagues believed that the trick of this fruit fly, was to move it’s wings back and forth to mimic running ants, when a natural enemy approached. The enemy would be irritated and would disappear. But Howarth could not quite believe this, because the fruit fly could simply fly away, as soon as an enemy approached. He remembered the drill fly, which has spin-like patterns on its wings. In this case, it was clear that an enemy would be frightened, for example a spider, when realizing, that these are his fellow-species. But what about the case of the fruit flie with it’s ants? It was like a mystery for him. Dr. Howarth therefore assumed, that all of this has a more sexual function:

“As soon as a male sees a female, many flies simply try to jump on the female. This special fruit fly, on the other hand, can enchant a male with his interesting wing play.”

He believed, that this is the reason for all of them. The more beautiful the wing-drawing, the more successful the insect is in propagation, thus securing its continuity. The fact is, that none of the scientists really knows, how the picture of an ant actually got onto the wings of the fruit fly. Nature had obviously painted them. But how intelligent is nature? Charles Darwin would say that over the long period of evolution, this fruit fly has come to this ant drawing, because it was more successful. But there is still the question: Why ants? Wouldn’t spiders, dragonflies, or snakes be more advantageous? In this case, also Darwin had to admit, that his evolution theory is not really appropriate.

You also have to know, that at this point Darwin hoped, at an advanced age, that he is wrong with his. He was not absolutely behind his own theory. So it was presumably exaggerated and marketed by other scientists. In addition to Darwin, another evolutionary theorist, Jean Baptiste de Lamarck, still exists. He thought, that a giraffe would have a long neck, because she always had a short neck before and always wanted to be able to eat the juicy leaves in the tree crowns. This desire was inherited genetically to the children, who were then given an ever-longer neck from generation to generation. Thus, Lamarck believed in the impulse of perfection, primarily in the animal world. In the human world, he argued, it would be similar, because for no other reason the human learned to be able to walk upright and straight, because he wished to be able to do so.

Thus, for a long time, Darwin’s theory “The Strongest Survives” was against Lamarck’s theory “The wishful thinking determines evolution“. Personally, I agree more to Lamarck than to Darwin, since Lamarck at least addresses the inner desire of the human being to develop further and to become more perfect and thus be reflected in the genes.

I would like to start with the question again from the beginning of the article: How did the ants came onto the wings of these fruit flies? Every wish and every thought, every feeling and every expectation, programs the DNA in the course of life. This applies to every living thing in the universe. Moreover, it is the desire and the longing and the faith, which causes a living creature, also plants, to achieve something. Thus the fruit flies are having ants on their wings, because they wanted it. The desire creates the reality of every living creature, the unyielding and consistent desire. Thus, the stronger wins theory, is not true, rather the beeing with the strongest will accomplishes what he wishes. The problem with our sciences is to always assume that everything is a matter of evolution, but this is not the case. It is a matter of the creator and of creating. Our world with all the people, animals and plants is a product of a planned creation. Thus also the wings of the mentioned fruit fly were created.
