A group of scientists have fitted tiny 3D glasses to praying mantises.

The experiment was carried out to prove that they use 3D vision to catch food.

The insects were put in a specially-designed insect cinema, and shown images of the kinds of bugs that they like to eat.

During the experiment the insects only tried to jump up and catch the bugs when the image was 3D, proving that they use 3D vision to hunt.

No preying mantises were hurt in the experiment as the scientists used blobs of harmless beeswax to fix green and blue lenses on the insects.
