It is for the first time till date, researchers have found the remains of parasitic wasps along with extinct and some unknown varieties in the fossils of fly pupae.
The wasp species that got extinct were endo-parasites, a sort of parasite that grows insides its host’s body. Perfectly as her nature describes, the scientists have named the one form the unknown parasitic wasp species as Xenomorphiaresurrecta, the type who’s named is derived from the movie Aliens.
Parasitic wasps those still exist in today’s time, laid her eggs on other insects that are the protection and most importantly the food for the young parasites. A variety of these parasites are endoparasites, which has a characteristic of injecting eggs inside the host body, where the larvae survive till it’s time of hatching, which ultimately leads to killing and most probably feeding on it.
Researchers along with the Karlsruhe Institute of Technology have participated in this newly released study in Nature Communications, sharing the discovery about the preserved larvae of the parasitic wasp inside its host (insect). An ultrafast x-ray device was utilized to find the parasitation which is not possible to see with naked eyes. A sum of 55 events of the existence of the parasitic wasps was recorded.
Among all these instanced, 4 extinct and unknown species of parasitic wasps were found, the most common in all the 55 instances was the Xenomorphiaresurrecta, which was discussed earlier.
The fossil of the insect was received from the Basels’ Natural History Museum, as well as from the Stockholm’s the Naturhistoriskariksmuseet. Around 1,500 instances of Puape of the size around 3mm in length were gathered from different sources. However, the fossils were originally collected in Quercy, France, into phosphorite mines.
A 3-mm insect’s fossil holds a secret of extinct parasitic wasp.
