? Hornet Argiope – Definition and Explanations

Introduction

L’hornet argiope (Argiope bruennichi), is also called striped argiope, argiope Where Eurasian spidera species (Species in life sciences (from Latin species, “type”…) An araneomorph spider belonging to the family Araneidae and genus Argiope. It was originally described as a species of the genus Araneus Before being classified as Argiope. Originally from the Mediterranean basin, the Argiope hornet is not only present in all areasEurope (Europe is a land area that…) central and northern as well America (America is a separate continent from Asia in the west and…) of North (North is the cardinal point against south.)in Asia (Asia is one of the five continents or part of the supercontinents of Eurasia or Afro-Eurasia…) also in Africa (With an area of ​​30,221,532 km2 including islands…) who’sWest (West is the cardinal point, opposite east.

Despite its camouflage yellow (There are (at least) five definitions of the color yellow, which are roughly the same…) and the black may act as a defense against predators who would mistake it for a hornet, a study showed that the alternation of yellow and black stripes on the body of this species actually doubles. number (The concept of number in linguistics is considered in the article “Number…”) from what they holdinsects (Insectes is a French-language journal of ecology and entomology…) acting as a visual decoy, making the spider less visible to its prey even though it is in the middle of its web. Argiope exhibits sexual dimorphism, the male being smaller and duller than the female.

Habitat and distribution

It is a species that appreciates an open and sunny environment. He caught it earlier south (South is the cardinal point against north.) of Europe (mainly south of the Loire in France), but – probably because of this Global Warming (Global warming is also called global warming or…) – tends to rise towards the north. It was first observed by a curator in Belgium in 1984 RNOB In Visé and in 2009 it appears to be present in large parts of northern France and Belgium, including the coldest regions. winter (Winter is one of the four seasons in temperate zones.) (Belgian Ardennes).

Reproduction

Argiope bruennichi is one of the species of spiders that engage in sexual cannibalism systematic (In the life sciences and natural history, systematics is the science for…) with more or less success and polyandry. At the end of the mating, the male voluntarily leaves the copulatory apparatus in 80% of cases, which reduces the chances of the rival fertilizing the same female and increases the chances of escaping from it and surviving after mating. Apparently, the genital apparatus of males of this species is particularly complex, esp point (graphic) structurally, it appears to play an important role not only in sperm transfer, but also in the female’s selection of her partner and the male’s ability to escape after mating due to predetermined points. is broken. After mating, the female quickly lays 200-300 eggs the cocoon (The cocoon is the envelope of the nymph of certain insects. It is also called the cocoon sac…) of color (Color is the eye’s subjective perception of one or more wave frequencies…) brown, consists of hairs of different biochemical structures, suspended in grass slightly above the ground. Eggs overwinter in a frost-free environment.

After the first molting, young spiders climb to the top of the branch and silk (Silk (textile fiber of animal origin) many insects, spiders…) virgin thread serves as a curtain and carries them through the air.

Behavior

Hornet argiope is an orbiting spider. It builds a geometric web (orbicular, close to a circle) to hunt vegetation (Vegetation is a collection of wild or cultivated plants (flora) that…)with one exception meter (meter (symbol m, from Greek metron, measure) is the basic unit of length…) of height (Height has several meanings depending on the subject area.) from the ground. Builds webs in tall grasses and fields empty land (Wasteland is land or territory that is no longer cultivated or cultivated, even…) or in hot, humid valleys. It is also found on the edge of the forest. This network has approximately one wire from 19 to 41 (usually 30). hour (An hour is a unit of time. The word also means magnitude…) morning or evening.

Many theories have been put forward to explain the existence of a stabilimentum, a pattern White (White is the color of a body heated to about 5000°C (see…) of silk inside zig zag which is on the internet. One of them suggests that it helps attract prey due to its high brightness in the ultraviolet spectrum that insects perceive. Another area of ​​denser silk is located in the center of the web. Another one theory (The word theory comes from the Greek word theorein and means “to think, observe,…” would explain the presence of stabilimenta to strengthen the canvas.

The spider immobilizes him predator (Prey is an organism that is caught alive and eaten by another after it is killed…) thanks to a poison (A poison is a poisonous substance that is a complex mixture of chemicals…) paralyzes. It is inoculated by means of hooks carried by chelicerae, which open a small opening at the top. As with other spiders, the Argiope digests the flesh of its prey thanks to its venom and especially the digestive juices that the spider regurgitates. It feeds mainly on grasshoppers, flies and bees and can eat up to four grasshoppers each. day (A day or day is the interval between sunrise and sunset; it…).
