Author 'Louise' (Id 187910 ) : In September, October or November, the female lays 200 to 300 eggs. She lays a white silk, close to the polyurethane foam, on a support such as a rod strong, a stone or a wall. Issued in a form that is white and creamy, this silk is brewed and set off by the valves of the genital area and takes the form of a structure in the lamellae. Once hardened and browned by oxidation, it protects the eggs until the spring. This structure is called the egg pod.
