  • THE orb web of the garden cross spider Araneus diadetnatus is made up of two types of thread with distinctive mechanical properties: stiff radial threads which sag when contracted by only 10%, and elastic circumferential 'capture' threads which can be contracted to less than 5% of their original length in the web without sagging1-5. Everyday silk is stiff, but can be plasticized by water6-9. It is known that capture threads are coated with a thin layer of aqueous glue10-12, and the question… CONTINUE READING
