3-weaving… Researchers have long been intrigued by the unique properties of spider silk, which is stronger than steel or Kevlar but far more flexible, stretching up to 40 percent of its normal length without breaking. Unfortunately, spider silk is extremely hard to mass produce: Unlike silk worms, which are easy to raise in captivity, spiders have a habit of chomping off each other’s heads when housed together.

1-spidersTo get as much silk as they needed, Godley and Peers began hiring dozens of spider handlers to collect wild arachnids and carefully harness them to the silk-extraction machine. “We had to find people who were willing to work with spiders,” Godley said, “because they bite.”

By the end of the project, Godley and Peers extracted silk from more than 1 million female golden orb spiders, which are abundant throughout Madagascar and known for the rich golden color of their silk. Because the spiders only produce silk during the rainy season, workers collected all the spiders between October and June.

Then an additional 12 people used hand-powered machines to extract the silk and weave it into 96-filament thread. Once the spiders had been milked, they were released into back into the wild, where Godley said it takes them about a week to regenerate their silk. “We can go back and re-silk the same spiders,” he said. “It’s like the gift that never stops giving.” …

Giant spiders give me the creeps. I would not want that job.
