Scientists will discover a new parasitic wasp that creates a zombie spider

In the Amazonian region of Ecuador, the newly discovered wasp becomes a regular social spider in a lonely ruined zombie.

Species of spider, Anelosimus eximius, create complicated cells like thousands of family members. It is considered a "social spider" because it cooperates with other spiders of its common home in sharing hunting, parenting and eating duties.

That is, until it is Zatypota a parasitoid wasp puts an egg on her stomach.

Once the seed had sprung up, the larva appeared, strapped to the spider and fed it, sucking blood like a hemolymph to survive. At this point, spider behavior changes and becomes a wrecked larva, leaving its common nest to create its own coconut net.

The larva feeds the spider until it disappears, in the relative safety of the cloth-shaped cloth that its host built before rewinding its own puppy and eventually emerging as a beautiful royal wasp.

Brutal.

Philippe Fernandez-Fournier noticed the strange behavior of the spider and began to investigate. Anelosimus eximius they usually do not leave their nest, but when he saw his stroll to create a completely new site, he was impressed.

His research, published in ecological entomology, suggests that the larva Zatypota the type of wasp is able to manipulate its host activity, control its behavior and force it to build these unusual networks – and this may be the most advanced behavioral manipulation ever seen.

Fernandez-Fournier and his research team suspect that the wasp causes a change in spider behavior by "knocking on a program of ancestor distraction" … which sounds terrible like brain control. Either the wasp or the spider causes the spiders to starve, making them look for food on the edge of the nest. Once they get out, they start spinning nets, unlike those they usually inhabit.

In the animal kingdom, the ability to make up new things is not. Other species of spiders, such as Orb Weaver, also become reluctant hosts for wasps and There are kinds of wasps that make it cockroaches, also. However, it seems that the newly discovered wasp has changed the building of the web site and the social behavior of this particular spider species much more intensely than before.

How can a larva be made? The answer to this question is not so easy, but several theories have been suggested, including the injection of hormones into the spider, which will abduct the host's tendency to create "diminished structures during displacement." Other types of parasitoid wasps disrupt the brain of the host with a chemical cocktail.

Scientists have also found that spider-size colony plays a role in a number of spiders receiving zombie treatment, with larger colonies seeing higher parasitic spiders. This may seem to be an obvious connection, but it is important to determine the dynamics between the parasite and the host and may allow for further understanding of the development mechanisms that play in a certain grim relationship.

Brutal.
