Ants fight with spiders for spheres of influence

---

Breeds: Myrmecia pyriformis and Delena cancerides. Habitat: The dry forests of eastern Australia, where spiders and ants wage an indefinite war of mutual destruction. It is unknown when the end of this confrontation will come. Imagine a picture of a female spider staying in a nest for several months and caring for her offspring until they become independent. The youngest of them still need many months of care, but the older ones are already ready to leave the shelter. Everything seems to be going well if they don't get kicked out overnight.

Bulldog ants attack the spider nest. They show no mercy. The female spider manages to kill several, but eventually she gives up. Retreating is the only option. But that's not enough for the ants. These spiders are their competitors, and they do not allow a new family to settle in the nest. Therefore, before they leave, they fill the nest with branches and leaves, making it completely uninhabitable. This scorched earth tactic ensures that ants don't have to compete with spiders for a long time.

Bulldog ants are the most dangerous ants on Earth according to the Guinness Book of World Records. Since 1936, 3 deaths of people from the bite of these ants have been registered. These are large ants, sometimes reaching a length of more than 2.5 centimeters, with a powerful bite and toxic venom. Bulldog ants live in colonies in the ground. Worker ants begin hunting at dusk and often for the entire night. They seem to use the same food as spiders. This puts them on a collision course with Avondale spiders, which hunt in the same places. The two species became mortal enemies.

Avondale spiders are also known as Huntsman flat spiders. They were used in the film Arachnophobia, where they "play" deadly spiders that invade one of the US cities. The producers chose them partly because they are harmless to humans and therefore safer to work with. But they will shock you when you first see them. An adult female can be the size of your palm, says Ip, a researcher from Israel. The width of 20 centimeters is mainly due to the limbs, which is quite normal. In addition, if you find one Avondale spider, it means that there is a colony of nests nearby. They are one of the few spiders that live in social groups, usually consisting of 100 individuals, but sometimes up to 300.

Each group consists of an adult female and several generations of her offspring, which take about a year to reach maturity. Young spiders sometimes move to neighboring colonies. But the spider neighbors don't accept everyone. They recognize strangers, and if the strangers are close to adulthood, they are likely to be attacked and even destroyed. Avondale spiders don't spin webs. They build their houses under the loose bark of dead fallen trees. Each spider usually hunts alone, but older juveniles share their food with younger siblings. Spiders have a slow metabolism, says Ip. This gives them an advantage, allowing them to survive with a reduced diet.

Ants have a fast metabolism and thus they need more food. Therefore, the presence of spiders can pose a real threat to them. Their only option is to destroy the spiders. Behavior that looks like an act of dominance may actually be an act of desperation. Jouez à chicken road en ligne et tentez votre chance.
