The rest of the scaffolding follows with many radii of nonsticky silk being constructed before a final spiral of sticky capture silk. There are several species in the New Orleans area. [9] The orb-web consists of a frame and supporting radii overlaid with a sticky capture spiral, and the silks used by orb-weaver spiders have exceptional mechanical properties to withstand the impact of flying prey. The females also tend to lay eggs near windows, so watching a small egg sac that will appear at the end of summer or fall is important.

These spiders only measure 2-3 millimeters long with their legs outstretched. If there was a poster child for spiders, it would probably be the orb weaver, which builds the familiar circular-shaped webs often found in gardens, fields, and forests.
