So if the web was made entirely out of dragline silk, an insect is very likely to just bounce right off. But by having really, really stretchy capture spiral silk, the web is actually able to absorb the impact of that intercepted prey.
Deci, daca panza ar fi facuta in intregime din din fire pentru deplasare, ar fi foarte probabil ca o insecta sa ricoseze de pe ea. Dar avand matase foarte, foarte elastica pentru captura spiralei, panza este de fapt capabila sa absoarba impactul prazii interceptate.
