Arjopa Brunnich: poisonous or not?

Spiders usually cause in most people either subconscious horror or disgust disgust. Arachnophobia, oddly enough, is very common. Theoretically - because spiders are poisonous. But! Of several thousand of their varieties of poisonous scrape from the strength of hundreds and a half, the rest for people are safe. The second explanation is an ugly look. However, the most dangerous spider - tarantula - resembles a plush toy. A small fellow tribesman, Arnupa Brunnich, in general is distinguished by a smart, almost festive look. So arachnophobia is something irrational, and spiders themselves are worthy of attention and interest, like any other work of nature.

Appearance of arhipipa

Even the fierce opponents of the Arachnids, the spider of the arianop Brunnich seems beautiful. In the people he is better known by other names: spider-wasp, spider-tiger, less often - spider-zebra. And all thanks to a bright, original, memorable color. In full accordance with the spider's constitution, the animal has a characteristic aspen (or tiger) coloring: yellow-black stripes. If you look closely, they interspersed with white lines, but from a distance the coloring completely corresponds to that of the wasps. The legs of the spider are also banded with contrasting stripes - a clear impression is created that stockings are stretched on them. Clearly on the fourth, if you count from the cephalothorax, the band has two notable tubercles, and along the edges of the abdomen there are notches (always six, but colored in different ways: the shades range from inexpressibly dark to bright orange).

Spider-wasps and the location of limbs are non-standard. Two pairs are oriented strictly forward, the other two are clearly back. Visually, there are no lateral supports, which is not typical for most arachnids, in which the legs are perpendicular to the surface.

Impressive dimensions of the arhipop Brunnich can not boast. Males never exceed seven millimeters in "growth" - most people will not notice them, especially since their color is rather dull. Female will be larger: can reach 2.5 centimeters, differing bright, from far noticeable colors.

How do these spiders live

The range, which the spider of the arianopa Bryunnich has confidently mastered, is quite wide. It includes many countries of Europe, the south (and, more recently, the middle belt) of Russia, the Crimea, the north of Africa, the South Asian territories, Japan and China. These spiders are lodged in meadows, on the roadside even of rather brisk roads, on the fringes, in the channels of parched rivulets. Arhiopa - the trapping spider; From an ambush does not hunt, but waits for prey in nets. The basis of the diet for him are grasshoppers, flies, filly and wasps.

Skillful cleavers

Like all network spiders, Brunnich's argyopa prepares traps stretched between the grass and the low-lying branches of the bushes. The networks of this species of arachnids are circular, in the center they have a zigzag-like pattern characteristic of the weaving of all the brothers of the genus Argiope and called stabilizumum. Despite the small size of the hunter, the traps in him turn out to be very strong, able to hold a grasshopper, which is larger than a predator in 2-3 times. On the creation of networks that are spinning at the time of sunset, in the approaching twilight, Brunnich's arhip is spending only an hour.

Spider Hunt Rules

It is not enough simply to weave the network for waiting for the extraction of arhiops. The owner of the trap sits in its center, in that same zigzag segment, and waits for the victim, holding the hank of the threads created in the limbs. When prey is caught, the hunter entangles it with cobwebs and bites. The insect dies of poison; In parallel, it begins to partially digest, while not yet in the spider's sponge.

Sad reproduction

Spiders of the species Arhipop Brunnich deal with the issue of leaving the offspring during the moulting period, when the female has already dropped the previous chitin, and the new one has not yet been overgrown. After the male has done his work, the partner in the vast majority of cases eats it. Sometimes the "brave fellow" succeeds in fertilizing the second lady, but up to the third approach, according to scientists, none survived. There is a theory that the cannibalism of a spider's weaker sex is caused by the lack of protein necessary for the development of heirs. However, it is not worth much sympathy for their "men": the female-arpyopa experiences her "husband" for a short time. After the creation of cocoons and the laying of eggs in them (up to 400 pieces in each "jug"), the spider-bird dies. Offspring also hibernate in the houses created by her, and in spring they are selected from them completely independent.

The spider of Brunnich Arpiopia: poisonous or not?

The question of the potential danger of the entire creeping brethren excites people in the first place. I did not escape such a fate and Arjopa Brunnich. Poisonous or not, this species of spiders, ask incorrectly. Strictly speaking, all the Arachnids are poisonous, another thing is that not all species of the species are able to bite the skin so that their poison reaches at least to the capillaries. So, even without conducting laboratory tests, it is possible to say with certainty that Brunnich Argyopa is a poisonous insect. In the end, it is the poison that "pacifies" its victims. And for insects, it is deadly. Another thing is a person. Its dimensions are incomparable with those that have the Brunnich Argyopa. The bite of this spider, therefore, for humans is relatively harmless. It can be compared to stinging the spider (the spider justifies its second name). The sensations are quite painful, swelling and itching can subsequently occur, but there is no danger of stinging the arpyopa. It can suffer from it unless allergic. But the same trouble will be brought to him by the bite of any insect, down to a mosquito.
