Silk is the secret weapon of the undergrowth. From the protective stalks of lacewing eggs, to the hanging threads of glow-worms, insects use it in an amazing variety of ways. Silk is stronger than a steel thread of the same diameter but, unlike steel, it's elastic. Witness the spiders who have taken the use of this extraordinary material to its extremes.
