The more beautiful the spider web is, the more toxic it is.
A study published in the journal Animal Behavior shows that not only people buy home decorations, but also small spiders know how to decorate their "apartments".
Ribbons, silk, red and green ornaments seem to remind people of splendid Christmas trees, no one thought it could appear in the spherical spider web. However, behind these beautiful things lies a great danger.
Researchers have discovered that, similar to human eyes attracted to glittering things decorated on holidays, the prey of spiders is also attracted to death by colorful decorations. its.
Daiqin Li, an associate professor of biological sciences at the National University of Singapore, said: 'This is the first study to show that the decoration from tree debris is used as a signal to attract prey.'
Spiders decorate its network to lure predators.
The debris here consists of pieces of leaves, flowers, bark and anything that has material from the plants that this spider cleverly chooses to decorate its network.
Scientists have focused on studying Cyclosa ginnaga and found that along with ornaments made of silk, residual prey, egg bags, materials made from trees provide complete details. finally for spider web.
Li and his colleagues conducted research both in the laboratory and in practice.
The most recent is studying how victims of spiders reacted to decorations on its network at Xishuangbanna forest, China. Scientists found that a decorated spider web placed anywhere 200-230% has succeeded in attracting more insects with untreated spider webs.
Li said: 'The silk system is made of spiders after being transformed into a lattice often loosely linked in a spiral, the circle depends on the species. For materials from trees, spiders use silk to bind debris to its webs. '
One theory is why spiders with attractive grids retain better food, and can hide behind decorations to hide prey and predatory birds. ?
Li and colleagues discovered nothing was the secret behind the success of the spider. Continuing to study the visual systems of typical spiders and prey like bees, scientists determined that both groups could easily detect spiders and decorations. its.
Mariella Herberstein, a senior lecturer at Macquarie University's Department of Biology, has done a lot of research on spiders and is an expert in this field, saying: 'The reason may be due to the ultraviolet components in color signals. Insects are attracted to ultraviolet strips and cannot not fly towards UV light. "
Li and his colleagues also found silver spiders' abdomen increasing color contrast between spider webs and surrounding decorations.
