I’ve seen the spiders, and they are us. Actually, they are better than us in their tenacity to rebuild after every assault. When you consider that a wave of a hand, a cloud burst, a wing swooping through the maze of silk can destroy hours of labor, it’s inspirational to watch their pure pragmatism in motion — no value judgments, no whining. Just the claw of the spider, hooking each line from the silk gland, wrapping it around the last thread, and repeating the cycle whenever the silks fray or fall.
I shot this with my Panasonic FZ50 (bridge camera), fitted with my Raynox DCR-150 for macro effect. The toughest part about using this lens is the tiny sweet spot. Hand held, it’s an exercise in isometrics, holding still and focused enough to keep the spider from moving into blur. I took the video this morning, after rain.
Spider silk is a multi-use protein fiber which starts out as a liquid in the spider’s abdomen. It’s used for webs, for protecting young, for wrapping prey, for ballooning, for draglines. And, it’s a substance we’ve been unable to synthesize, stronger than Kevlar. It is the alignment of glycine and alanine that accounts for the spider silk’s strength.
Other Spider Silk Factoids:
- More than a million Golden Orb Spiders spun a textile on display last year at the Museum of Natural History in New York.
- Researchers are getting closer to emulating the properties of dragline silk.
- Scientists used nuclear magnetic resonance spectroscopy to determine how spiders can instantly spin liquid proteins into webs.
- The oldest known strand of spider silk was found in a piece of Lebanese amber, dating to the Cretaceous Period.
- Samuel Zschokke, of the University of Basel, put together a web construction gallery, showing the building process for a variety of webs, based on recorded movies of the spiders.
- The build of a spider’s leg probably helps him or her navigate the web threads.
- Will Knight of Knight’s Spider Web Farm makes products using the real silks of woven webs.
