Nature shows once again how marvelous yet at the same time wicked it can get. Scientists have just discovered a new species of wasp that has a one of a kind lifestyle. They are described as both manipulators and parasitic developing a unique type of behavior. Their life is so full of dangers that they are battling to stay alive right from their birth. These parasitic wasps seem like a scary subject for a horror movie.
The gall wasps are leading a normal life by taking cover inside oak trees. This way of living can damage the flora as they infest the trees. However, they do not compare in ferocity with their main enemies, the Euderus set. These newly discovered species are relying on the gall wasps to dig protective tunnels in the stem of the oak. In the inside, they start laying eggs. After half of year, young gall wasps are strong enough to chew their own way to the surface to meet the new world.
However, scientists discovered that not all specimens arrive at their destination safely. Many of them remain with their heads stuck just at the exit of their crypts. Afterward, they suddenly die. Scientists soon discovered the terrifying cause of their death. It seems that these parasites are in their turn used by other parasites. The Euderus sets are using the heads of the gall wasps to lay their eggs. The larvas are starting chewing their way out of the hosts’ head when they are mature enough to get out.
The head of the host blocking the entrance of the crypt is the perfect protection system for the set larvas. There are fewer chances for predators to enter the crypt and devour the gall wasps as well as the parasitic wasps. However, scientists found that not all Euderus sets survive in their turn. If the young gall wasps succumb before they manage to make a hole in the bark, the larvas will have three times smaller changes to get out alive. Scientists are of the opinion that their jaws are not strong enough to dig or they are born too weak to penetrate the bark. This would explain why Euderus sets need a host to dig tunnels for them in the stem of the oak.
