The Spider Web That Gets Stronger When it Touches Insects

by admin June 13, 2017

There’s a species of spider – the cribellate spider, that weaves its webs differently to other spiders. The threads of these webs are more silky, extremely fine and a hundred times thinner than regular spider silk.

The silk has a fuzzy, woolly texture and is without any glue. These dry threads are still sticky and effective in trapping spiders.

Researchers at Aachen University in German have found that cribellate silk adheres to insects in a previously unknown and strange way.

When the prey touches the strands of the web, waxy chemicals get sucked into the woolly nanofibers and reinforce them. This turns the mangled threads into a solid rope. The prey becomes a part of the web, strengthening the web. Find out more https://www.theatlantic.com/science/archive/2017/05/crebillate-spider-web/528585/
