Cross-Spider in Its Web (image) University of California - Berkeley Caption This shows a cross-spider, Araneus diadematus, in its orb web. Like many spiders, this species produces several types of silk: a stiff kind for the radial spokes of the web, and a more flexible one for the spirals. The flexible silk is easily deformed by the electrostatic charge of nearby insects, increasing the effectiveness of the web at capturing prey.
