Orb Weavers build large, strong, vertical orb webs. Generally, the spider constructs its web in the evenings and takes it down again at dawn. The spider rests head-down in the centre of the web, waiting for prey. During the day, the spider rests on nearby foliage with its legs drawn under the body. Flying insects such as flies, beetles and bugs are common prey. Butterflies and day-active moths are sometimes caught but are partially protected from web entrapment by the presence of scales on their wings – these scales can be shed and this may allow the insect to struggle free of the sticky web. The female of the Nephila species greatly out-sizes the male. So, very often the male Nephila spider is mistaken for an offspring when it is found on the web with the female because of its small size and different color.
Las arañas tejedoras del género Nephila como este espécimen construyen grandes telas verticales relativamente fuertes. Generalmente el animal las teje durante el atardecer y las retira al amanecer. Durante el día descansa en el foliage con sus patas retraídas. Los insectos voladores tales como las moscas, los escarabajos y otros insectos de porte pequeña son sus presas usuales. Mariposas y polillas pueden caer en su trampa pero están relativamente protegidas dado que sus escamas se adhieren a la misma y se escapan fácilmente. La hembra de las especies Nephila superan en tamaño a los machos. Debido a ello se los confunde con su prole también por su diferente color.
