Black and yellow spider, which are very useful to construct large networks residents in a home garden. Spiders that construct complicated paths called spiders. The black and yellow species widely distributed throughout North America is commonly referred to as a golden orb weaver spider or writing. Like all spiders, they are carnivorous predators feed on a variety of insect pests in home gardens. However, they are not dangerous to humans or pets.
Female black and yellow garden spiders are much larger than males. Adult females can be up to 1 long 1/2 inches, while males grow long only to 1/4 inch. Both sexes have a conspicuous yellow pattern on a solid black abdomen. The front part of the body – called cephalothorax – has many small, shiny hair, which an iridescent sheen. The legs are long and slender and are black plain color.
Argiope aurantia, or golden orb spiders get their common name from a habit of building large, complex, circular orbits in home gardens. The spiders build webs in sunny areas that are protected from wind. The spiders build webs up to 2 feet in diameter, containing a dense network of radial structures. When a web is formed, the web is in the middle of the web and spread the legs in pairs, so that it appears to have four instead of two legs. The spider is in the same place, it is because their network is always disturbed, or if they are not able to catch enough food to support themselves.
Black and yellow garden spiders are beneficial to gardens. The spiders wait patiently in their networks for insects such as aphids, flies, mosquitoes and other pests. When an insect flies in a web, the orb weaver quickly climbs on the web and bites the trapped insects and fine silk weaves a blanket over her. Orb weavers incapacitate prey caused by injecting poison, paralysis. The poison begins to digest the prey even before the spider eats it.
While golden orb weavers are not dangerous to humans or pets, their big cars are often a nuisance to deal with outdoor work areas. While she is able to bite, black and yellow garden spiders are not aggressive and will not bite unless provoked. Golden Orb weaver spider bites result only minor skin irritation, similar to a bee sting.
