A field study of the ecology and natural history of the spider, Nephila clavipes, was conducted between May 1972 and September 1973. The habitat of Nephila clavipes on the Texas Coastal Plain is described, as well as its life cycle, monthly variation in selected web parameters, and abundance in a study area. Height of the web aboveground, magnetic orientation, degree of slant, and density of weblines all exhibited consistent changes during the year. Numerical density of the spiders was approximately constant during the year, suggesting that adult female Nephila are relatively immune to predation and that there are only a finite number of suitable web sites within the study area.
