Spider agriope It seems to be an unremarkable spider. It so merges with the external background that sometimes it becomes completely invisible in the grass. This insect belongs to those spiders that live next to us. Its biological name is associated with the Danish zoologist Morten Tranje Brunnich and completely sounds spider Agriop Brunnich.
Features and habitat
This insect belongs to the garden spider-weaver. What are they characterized by? To catch their victim, they make a fishing net of rather large sizes, circular in shape with a spiral center.
This middle is clearly visible in ultraviolet rays, so it is especially attractive to various insects. Bugs and bugs see her from afar, unsuspectingly moving in her direction and falling into the spider's web.
Their appearance is very similar to a zebra or wasp, therefore Agriopa is called a spider-wasp. The body of the spider is covered with alternating stripes of black and yellow. This feature applies only to females.
Male agriopes completely nondescript and no different, usually light beige. Two strips of dark tones can hardly be seen on his body. Pronounced dimorphism between the sexes in this case on the face. The body length of the female is from 15 to 30 mm. Her male is three times smaller.
Sometimes you can hear how they are also called tiger, wasp spiders. All names are given by these arachnids due to their coloring. They look very nice on the leaves of the plant.
The head of the spider is black. Throughout the cephalothorax, dense hairs of ash tones are observed. The legs of the females are long black with yellow accents. In total, the spiders have 6 limbs, of which 4 they use to move, one pair to grab the victim, and another pair to touch everything around.
From the respiratory organs of spiders, a pair of lungs and tracheas can be distinguished.Agriope black and yellow - This is one of the most numerous spiders. Their wide distribution is observed in many territories - they have populated the countries of North Africa, Asia Minor and Central Asia, India, China, Korea, Japan, the USA, some regions of Russia, and the Caucasus.
The movement of spiders to new territories has been observed recently due to a change in climatic conditions. Favorite places Agriopes Brunnichi lot. They love open, sunlit spaces, fields, lawns, roadsides, edges and forest glades.
In order to hunt a spider, you have to arrange your hunting nets. He does this on not too tall plants. Their spider webs can take the air currents so far that it is not difficult for spiders to travel along sufficiently large distances with them.
Thus, the southern populations move to the northern territories. It is worth paying tribute to the web of Agriope. In this case, the spider is perfect. Two patterns are observed in the web, diverging from the middle and located opposite each other. This uniqueness of her is a real trap for victims of the spider.
Spiders can make such beauty thanks to the unusual structure of the limbs, on the last pair of which there are three simple claws with serrated bristles and a special appendage in the form of a spike, which weaves intricate patterns from the web.
If you look at photo Agriope lobata you can immediately identify the female, not only by her special color, but also by the fact that she is usually in the center of the web, most often upside down, resembling the letter "X".
Character and lifestyle
To weave its web, a spider Agriope Lobata basically chooses twilight time. It usually takes him about an hour to do this. Most often, its web can be seen between plants about 30 cm from the surface of the earth. This arachnid is well aware of the danger. In this case, the spider leaves the fruits of its labors and hides on the ground by flight.
Spiders usually create small colonies in which no more than 20 individuals live. Their web can be entangled with several plants in a row. Such tactics help you to catch a victim for sure. The fixing of the main threads is observed on the stems. The network cells are quite small, differing in the beauty of the pattern, in principle, this is typical for all orbits.
The spider spends almost all of his free time either in the weaving of the web, or in anticipation of his victim. Usually they sit in the center of their cobweb trap or in its lower part. Morning and evening hours, as well as night time, become for this arachnid rest time. He was sluggish and inactive at that time.
Often people wonder - Agriope's spider is poisonous or not? The answer always sounds yes. Like many arachnids Agriope is poisonous. For many living things, his bite can be fatal.
As for humans, deaths after bite of man Agriope in practice was not observed. In fact, an arachnid can bite, especially a female. But its poison for humans is not so strong.
At the site of the bite, redness and swelling appears; in some cases, this place may become numb. After a couple of hours, the pain subsides, and the tumor disappears after a couple of days. A spider is dangerous to people suffering from allergies from insect bites.
In general, this is a very calm and peaceful creature, if not touched. It has been observed that females do not bite when they are sitting on their web. But, if you take them in hand, then they can bite.
There are many varieties of this spider. Many of them can be seen in terrariums. For example, it is very popular among people who are accustomed to breed outlandish creatures at home. Agriope lobulated or Agriope lobata.
This arachnid feeds on grasshoppers, flies and mosquitoes. They do not disdain other victims who have got to them in the network. As soon as the victim falls into the web of Agriop, he disables it with the help of his paralytic poison. In an instant, he wraps it in a cobweb and eats it just as quickly.
It is worth paying tribute to the quality of the arachnid web. It is so strong that seemingly rather big and strong grasshoppers are kept in it. Spiders and orthopterans love to eat.
Often, the male becomes the victim of the female Agriope. This can happen after mating. And if the male managed to escape from one female, then he probably will not hide from another and will be swallowed up like the most ordinary victim who got on the net, without a twinge of conscience and pity.
Reproduction and longevity
The mating season in spiders begins in mid-summer. From this time, the wandering of spiders in search of a female begins. Often they get into the living room, trying to hide. The breeding season is an increased danger for males, which may lose their limbs and even life.
The thing is that the aggressiveness of the female increases after mating has occurred. This feature is not observed in all species of Agriope. Among them are those who live with each other until the end of their days.
A month after mating, the female lays eggs, forming for them a brown cocoon. The appearance of young spiders from it is observed next spring. The female dies after the appearance of the offspring.
From the foregoing, it should be concluded that Agriopa does not constitute a great danger to man; he should not be exterminated at a meeting. Also, do not bother and worry about the ruined web accidentally caught in the way of it. These arachnids can make such a masterpiece in literally an hour, or even less.
