Like the Horror movie, This Ant decorates the nest with an enemy skull

[ad_1] – Florida Ants (Formica archboldii) It has been the subject of research for more than 60 years. After being proclaimed a special species in 1958, scientists have uncovered many unique things about this ant, including the habit of decorating their nest with the skulls of their enemies.

The skull found in this anthill nest comes from captured ants or Odontomachus. This species is known as a malignant predator and is not an easy opponent for other ants. That's why researchers are also speculating F archboldi they only occupy the abandoned traps of captured ants.

However, there are other speculations that indicate this F archboldi can be a predator who specializes in hunting Odontomachus.

This mystery finally found a bright spot when Adrian Smith, a researcher at the State University of North Carolina, studied ants F archboldi.

"This is a study that was created by reading observations in 60 years of research. The possibility is that the head of the ants is not accidental in Formica's nest and that there are some interesting biological facts behind this record of natural history," Smith said. Science DailiOn Friday (November 16, 2013).

Use video time period, Smith discovered that they are ants F archboldi can really kill trapped ants. Even more astounding, F archboldi capable of imitating a strategy of captured ant and spraying formic acid.

"Scientificly surprising discovery from this study is that these ants can chemically imitate chemical profiles of two types of trapped ants, which is truly unusual for ants that show a lot of variations in chemical signs," said Smith, whose research was published in the journal Sociauk Insectes.

"In addition, chemical mimicry is usually a tactic used by parasites, but there is no evidence that F. archboldi is a parasitic species, "he said again.

Smith discovered that preventing the prevention of formic acid belongs F. archboldi This quickly leads to the dulling of the ants and paralysis of their bodies. Video observations later revealed that the captured ants that just paralyzed had pulled into the nest and had their head scratched.

However, there is no evidence for finding a direct link between this behavior and its possibilities F archboldi as predators who eat their enemies. This chemical imitation probably indicates a long evolutionary history between these ant species.

"Prior to this research, F. archboldi known only as a type with a habit of gathering heads. Now we have what can be a model of species for understanding the evolution of chemical diversification and mimicry, "Smith said.

He also said that more efforts are needed to understand the relationship between F. archboldi and captured ants, and what are the advantages of this behavior.
