In a "Nature" study, British biologists debunk the complexity of mimicry techniques in insects. Why do some symphs, these yellow and black striped flies, mimic their models so badly, wasps? To understand this, researchers have printed dozens of insects in 3D.
The imitation game: Why some species are better at fooling predators than others
Experts from the University of Nottingham have created life-size 3D-printed insect models to explore how some species trick predators into thinking they're more dangerous than they really are—and avoid being eaten as a result.
In the eye of the viewer: Some harmless animals imitate the appearance of more dangerous species in order to deter predators. However, whether this camouflage strategy works out, decides less the degree of perfection of the copy than rather the attention and view of the robbers, as evidenced by an experiment. For example, birds can distinguish very precisely between "original" and "fake", whereas spiders recognize the subtle differences worse an…
