String spider webs are fascinating structures made from a single strand of silk. They are often used to catch prey, but can also be used for shelter or to store food. String spider webs are made by a variety of spider species, including the common house spider (Achaearanea tepidariorum) and the golden orb weaver (Nephila clavipes).
To make a string spider web, the spider first spins a frame of silk. This frame is usually made of several spokes that radiate out from a central point. The spider then spins a series of concentric circles around the frame. These circles are connected by radial threads, which run from the center of the web to the outer edge.
