A recently discovered wasp can apparently control the minds of its victims.
Euderus set, also known as the Crypt Guard Wasp, has the incredible ability to control the actions of multiple species of bile wasps, allowing them to be parasitized and dying horribly.
Galls are abnormal tumors resembling tumors on oaks created by bile wasps to shelter their larvae. Once the wasp larvae become adults, they feed on them to escape and fly away. The guardian wasp of the crypt (named after the Egyptian god Set who trapped his brother in a crypt before killing him) also lays his eggs in the gall. The crypt guardian larvae then sink into the newborns of the biliary wasp.

A host wasp matures and begins to sneak as usual, but as observed by researchers from the University of Iowa and Rice University, it happens something strange: the host wasp stops gnawing a hole only big enough so that his head can pass through.
"When the biliary wasp is attacked by Euderus (the guardian of the crypt), she always starts gnawing an exit hole but fails to emerge and results in what we have called a" head shot "," l & # 39, lead author of the study, Anna Ward of the University of Iowa, told Fox News. "We identified headaches due to the observation of wasps that had stopped chewing their outlets and were no longer responding – and we visually looked like a wasp's head blocking a hole in the bump.
After feeding on the body of the biliary wasp from the inside, the wasp, guardian of the crypts, burrows out of the host's head. Alien, devour your heart.
What is disconcerting to the researchers is that the guardian larvae of the crypt, once inside the wasp, somehow manipulates its host to eat such a small hole, leaving that the head of it exposed.
"Currently, we are not sure of the mechanism in which E. set manipulates his host," Ward explained. "We expect it to be a simple mechanism of stopping or paralyzing the host at the right moment when he chewed a part of the exit hole, but before he came out."

To study this phenomenon, the researchers had the odious task of collecting galls in the wild, eventually collecting more than 23,000 wasp-based shelters containing more than 100 species of gall wasps, as well as crypt guardians. According to Ward, picking up the galls themselves was not that difficult.
"Oak galls are quite common in North America and are found on all species of oaks," she said. "In order to collect the wasps, we simply collect the galls that the wasp grows inside."
The team then brought these galls back to their lab and waited for the wasps to emerge, where they could observe occasional observation of a crypt guardian wasp. They finally watched the crypt guards come out of the head of 305 wasps belonging to seven different species of wasps.
The guardians of the crypt also made sensitive choices about their victims, preferring biliary wasps without spikes or fur on their bodies.
