The death grip bite leaves a very distinct scar on the leaves. This prompted Dr Hughes, together with research partners Conrad Labandeira from the Smithsonian Institution in the USA and Torsten Wappler, from the Steinmann Institute in Germany, to search for potential evidence of the fungus at work by studying the fossilised remains of leaves.
After studying leaf fossils from the Messel Pit, a site on the eastern side of the Rhine Rift Valley in Hesse, Germany, they found clear evidence of the death grip bite in a 48-million-year-old leaf specimen.
If you are unaware of what "zombie ants" are, there is a fungus that infects the brain of ants and takes control. The ant is then compelled to climb to a prime location on a leaf and clamp down with a "death grip". In their last hours, infected ants move towards the underside of the leaf they are on and lock their mandibles in a 'death grip' around the central vein, immobilising themselves and locking the fungus in position. The fungus cannot grow high up in the canopy or on the forest floor, but infected ants often die on leaves midway between the two, where the humidity and temperature suit the fungus. Once an ant has died, the fungus sprouts from its head and produces a pod of spores, which are fired at night on to the forest floor, where they can infect other ants.

Not a sunrise, but a galaxy rise
