Hearing the word silk, most of us will imagine floss, the flexible weavable fibre gained from moth caterpillar. However, many other organisms also provide a fibrous material, which is an expensive and valued silk fabric: several moth larvae excrete silk. Even the spider thread or the Mediterranean native Pinna nobilis bisus thread can be used to produce fabric. Fabrics made of exotic lotus silk, agave silk or the milkweed crop silks are representatives of the rare plant silk.
