Marvel of nature
A spider web is a true marvel of nature. The animals connect several widely spaced points with thin, elastic silk threads.
The flying thread that results from this procedure consists of a bundle of 50 to 60 individual threads, each of which is just 250 nanometers thick. That's 200 times thinner than a human hair. Due to its special structure, even a small gust of wind is enough to set the flying thread in motion. With the first movements, the spider releases more and more thread from its spinnerets, until the flying thread gets stuck somewhere. However, a spider cannot influence the direction in which the flying thread is carried, it depends solely on the wind direction.
The spider proceeds systematically and routinely when setting up the entire orb network. The construction of a new cycle network takes between 20 and 30 minutes, depending on the size. The flying thread of a horned garden spider can be up to 50 centimeters long. Since spiders are mostly loners and cannibalistic catch and eat their own kind, they are usually careful not to get in the way of other webs and spiders when stretching a new web.However, there are exceptions, such as what is probably the largest spider web in the world discovered by researchers in September 2018. It wasn't a single one, but a 300-meter stretch of coast in the Greek lagoon city of Etolikos was completely enshrouded in spider webs. A large number of favorable conditions had prompted the so-called Strecker spiders to create this unusual web network.
By the way: Researchers discovered what is probably the largest web ever made by a spider in Madagascar in 2009. Caerostris darwini ("Darwin's bark spider"), which is only 20 millimeters in size, builds webs that reach across rivers. The bridge thread can reach a length of up to 25 meters.
