prey. Finally, she remodels the center of the web – the hub – which connects to the signal thread as a prey detection device for the spider which lay in wait in her retreat. Web longevity Juvenile Z. x-notata spiders have been found to rebuild their webs daily in order to catch prey. Web renewal typically occur at the end of the night for both juvenile and adult spiders. Generally, the longevity of Zygiella x-notata webs is approximately one day. Influence of aging and experience on web construction Multiple studies have shown that the composition and construction frequency of Zygiella x-notata orb webs change with increasing age and experience in the resident female. Anotaux et al. determined that older Z. x-notata spiders invest less silk in the production of their webs as compared to younger spiders in both short- and long-lived varieties. Older adult female spiders were also found to have greater variation in their orb webs than younger adult females, reflecting a decline in locomotor functioning correlated with increased web irregularity in older age. Venner et al. established a correlation between prey capture and ingestion, and web rebuilding practices among adult female Z. x-notata. Spiders who engaged in the four stages of predatory behavior and subsequently rebuilt their webs were found to invest less in the capture area of their newly built web. Web anomalies Spiders of the species Zygiella x-notata consider previous elements of web construction in the building of future webs. This is an imperfect process, susceptible to web building errors. Anomalies in web structure among this species have been found to result from positional modification of a spider on the radial strands of the web. When the spider's fourth leg is oriented peripherally to the web during web building, opposite the hub of the web, anomalies in web construction are common. In this position, the spider cannot detect the correct attachment position of the inner spiral to the next radial thread. Web anomalies are detrimental to spider success, as they can alter the performance of the web, including both prey capture ability and predation avoidance. Characteristic missing web sector Zygiella x-notata is known for its flexibility in web building with the missed sector orb webs that are woven by this species. Even though the web construction behaviors are innate, there is a characteristic flexibility in these spiders when they alter their webs according to their advantage
